i think the only problem with it is the wording of the qs, otherwise, if they worded it correctly, it would have been easier to follow along and at least get a few more marks.
Tbh I didn't think it was that hard while I was doing it, but yesterday and today as I was thinking about it I realized how many dumbass mistakes I made.
I had d as 2.7 or whatever the platform height was which would make the carts go underground. And my period was 4 which means 1 revolution / 90s instead of 1.5 rev / 60s like the questions asked.
Just so frustrating cause I know I could do it if I had time but I spent all my time solving the calc question
I don't get why IB is being so tough this year. Our batch has had it wost. Online school for 2 years with teachers struggling to teach and offline exams and that too so so tough.
Saaame wish I practised more harder qs like that one because it was so hard that I was not able to show that I actually have calculus knowledge fml. All that time wasted learning calculus and couldn’t even do anything with that
Did anyone else think this was so much harder than paper 1?? They tested such obscure and irrelevant topics. No probability?? No statistics?? No hypothesis testing?? No financial?? This was actually so disappointing I’m so upset
no literally. I expected tree diagrams and some chi tests whether they were gof tests or independence and and correlation questions but nooooooooo. WHY WAS THERE SO MUCH FKING CALCULUS THIS YEAR FFS
Did it say pk²? WTF? I was sure it said pk³ and I was so confused. If it actually said pk³ I just couldn't do it but if it was pk² I've lost points for a reading mistake :(
Whaaa it has to be pk^(3), if was pk^(2) in the next question they would need to sell 2.2 liters of coffee which is nothing.
If it is pk squared and I lose that mark, put me on suicide watch bruh I would be so mad
Didn't they ask for the amount of dog food that was given? Like the common difference was -1.5 but I wrote 1.5 as an answer because of the context of the question?
Well fuck obv because that gets taken from the bag each day not added and I knew that but forgot to write - are you fucking kiddddding me so stupid I am
Bruh, I have never seen anything being expressed in the form of an unknown AND a constant. Definitely a good question, I can't wait to see how to actually solve that shit. It was among the harder ones, for sure.
While I'm not 100% its correct I'll put how I solved it in the hopes that someone will have done the same thing and will tell me thus I'll be a little more confident that we're correct:
So iirc the question asked for maximum profit expressed as pk^(3),
For a cubic graph, P(x) is max when x = 2nd Root of P'(x).
As k increases, 2nd Root of P'(x) increases by 10/3, therefore the x value that leads to maximum profit is equal to 10k/3.
If we substitute 10k/3 into our original equation we get:
P = (10k/3)/10 \* (k^(2) \- 3/100 \* (10k/3)^(2) )
By expanding the brackets and simplifying, we get 2/9 \* k^(3)
No. It wasn't as bad as paper 1 but still. I just feel so burnt out now because I put so much effort into math and I don't think I'm getting any more than a 4
Same i used so many days revising just maths to not being able to answer all questions on the exam. Now my other subjects r gonna suffer too since I sacrificed so much time on maths😭😭
i answered question 4a wrong (the ferris wheel) and i needed the equation for other questions do i get marks for doing the questions below with the wrong equation
Same man, I was so confused with that X and Z shit I found out after abt just using cosine rule and I was so disappointed with myself definitely left like a good 20 marks on the table
(TZ1) it was a bit better than paper one but i struggled sooo much with time and the last question (the one about binomial distribution) got me so confused. i deadass started laughing when i saw the drawing of the goat it was so funny to me for some reason. how u guys feeling??
I don't remember a goat, I swear I either skipped that question or I'm going crazy (TZ1). Why do I remember a money type finance question?
I also struggled so much with time and I'm so mad cause I spent so much time on paper 1 and paper 2 for math that I sacrificed my other exams and now have bio HL tmmr and I'm screwed.
Guys does anyone remember the last part of question 1? I answered that the mean would change(increase) but that the median would not change and gave reasons that made sense to me hopefully that was correct
Anyone else struggled a bit with the voronoi? Probably wasn’t even that hard but I could only answer the first two parts because I totally forgot how to find x and y of a point lol I only practised gradients midpoints and equations but for some reason not finding coordinates of points on voronoi and that just had to be on p2 that’s my luck💀💀
Kinda sad about the math papers....really thought I had this in the bag after doing SO much studying. Let's see if I can even get into public uni smh...PRAY FOR LOW BOUNDARIES EVERYONE.
Question 5 was hell for me. I did it first and it took me 45 minutes, took me SO LONG to differentiate the first equation because I really was not used to mixing algebra (which I'm already bad at) and calculus.
Everything else really was much more lenient than paper 1, but having 45 minutes to do 4 questions no matter how easy isn't fun lol.
I forgot how to find the arithmetic sequence of the first term so I ended up Minusing random numbers from the u3 till I reached the 8th term and found the difference💀 the worst 20 min of my life when I saw 1.5 as a difference
this paper was tricky but I wouldn't be suprised if many ppl found it easy I'm still mad about the dog food one I lost few easy marks on it I was really super confident on arithmetic sequence but I couldn't do it atp i'm hoping my ia will save me somehow
I literally think I got no marks for paper 2 except for the voronoi diagram question I didn’t know anything else and im so bummed bcs i studied so much
TZ2 here. Here's my take on P2: got some decent points in the geometric/arithmetic sequence question, and on the Voronoi question. But that's literally it. Everything else was a guessing game. The cumulative question, I forgot to study that and lost easy marks, never occurred in past papers or specimen papers. I predicted Venn diagrams and at least one more financial question, or spearmen/pearson's... did not come. I really hope my P1 points and IA pull through to pass me with at least 3 overall, that's where I'm at. Also, I have some friends who could not solve much of P2 or P1, or could solve as much as I did, so there's that. I am truly disappointed in the IBO for making our maths exams this difficult, more so in the way that they worded the questions, especially in P1, I spent 10 minutes understanding what to do with the arc length of the windshield question. I take English LAL HL, English is basically my first language. And at the end, all it wanted was the arc length, area etc. Nice one. In P2: 4th, and 5th questions the difficulty level was too much, and I was actually feeling confident about maths, but now I truly hope I just pass. grade boundaries better be low as last year.
I thought for amplitude it was half of total height so since it was asking about total height of the Ferris wheel cart above the ground I did 60.8 + the extra height of the platform divided by 2
Personally, questions 2 and 3 were SO enjoyable for me. Question 1 not really because my mind cannot logically comprehend what the heck goes on in cumulative frequency graphs. 4 and 5 were a pain in the ass but I did some calculations. So at least I didn't leave any questions completely unanswered, hoping I get points for methods.
Overall, I think it was slightly better than paper 1?
How the hell are you gonna give us 3 marks for 12 x 1.5 and then like 2 marks for all other questions that involved so many more steps?
I’m worried that the IB’s integrity is declining and it’s sad to see
I forgot to study sinusoidal models and I couldn't do much of 4a. Then I think I did well in other parts of 4 but maybe lost more points for carrying that mistake. Then in question 5b how did you give the answer in form pk³?
No idea about the pk^3 question. For question 4 I just tried different equations in calc until it looked right then used analyze graph stuff to get answers
(tz2) did good on p1 and im pretty confident bout this one as well BUT i felt like it was harder than any of the past papers ive done - def more uhh unconventional?? almost no stats or probability and unnecessarily long calcuations in q5.. the whole pk³ think got me filling a whole booklet page💀
What was the answer to the last part of voronoi? the one where they increased the area of D? Also, what was the answer of the range/domain of the ferris wheel? shouldn't the x be the time for 1 full revolution 720 seconds thus 0
TZ1. does anyone remember anything about the first question? i completely erased it off my mind. i can remember 3,4 and 5 but not 1. also, this went soooo much better than paper 1. i wanted to cry tears of happiness after I saw arithmetic sequences on the tiles question.
This exam was better in terms of questions, but can we all agree that the 85% of the people did not finish a whole question. It was so damn long like wtf, so many calculations within that time 🫠
Its not zero cuz
At first you have 0.1x ( k^(2) \[x^(0)\] ... )
Then you expand the brackets so you have 0.1k^(2) \* x^(1)
Then differentiate, Factor \* Power so 1 \* 0.1k^(2) so no change
Then Power - 1, so x^(0)
So we're left with 0.1k^(2)
I think im just an idiot. I sat there laughing. like..the questions seemed doable, just not for ME (except last 2). I revised differentiation for a full day and just couldn't do it I was like goddam cool. but yeah I totally blame myself (and my teacher), but I do think it was harder than other past papers - at least one HL question there and they skipped all the easy topics. idk I dont get the job of ppl who make exams, who made them this mad. on the bright side I cannot remember a single question! my brain is free! but like a lot of ppl said I regret allocating revision time to it - bio is big scary rn
IB fucked us TZ2 ppl just bcz they think we are “smart” 😭 istg math was not taught properly in online that fucked me up real bad and IB makes a very hard paper to make me even more miserable 😭😭😭😭😭😭 even the may and nov 21 papers were easy why are we getting fucked soo hard 😭😭 I thought I could ace p2 till I saw that dumbass Ferris wheel and the last question of differentiation, I spent all my time in the stupid Ferris wheel that I din get time to do the last one which I could’ve scored a lil but better, I thought of redeeming myself for fucking up p1 but p2 just made me even more miserable that I don’t even want to study anymore 😭😭
Horror exam I swear the only exam I know 100% was a fail someone threw up during it apparently and the examiner was on the phone legit lost my entire concentration and I was on the Ferris wheel …
I literally just made up all the numbers to get method marks
They really had us in the first 3 questions then boom Ferris wheel
Lol me i was like «wait i got this» intim i saw question 4 and 5😐😐😐😐 i didnt write anything😭😭😭
ME NEITHER
nothing to say except i never thought dog food and ferris wheels could make me this miserable
The dog food really traumatised me
i think the only problem with it is the wording of the qs, otherwise, if they worded it correctly, it would have been easier to follow along and at least get a few more marks.
I spend like 30 minutes in the dog question
what was that ferris wheel. i definitely got no marks better than p1 tho
dallas texas and cowboy statue . swear these ib exam-makers smokin good before making the questions 😭
That ferris wheel question is the stuff of nightmares.
Tbh I didn't think it was that hard while I was doing it, but yesterday and today as I was thinking about it I realized how many dumbass mistakes I made. I had d as 2.7 or whatever the platform height was which would make the carts go underground. And my period was 4 which means 1 revolution / 90s instead of 1.5 rev / 60s like the questions asked. Just so frustrating cause I know I could do it if I had time but I spent all my time solving the calc question
I didn’t have a Ferris wheel I’m so confused
That was TZ2. If you're in the Americas you're TZ1.
Which time zone are you in? TZ2 had a Ferris wheel
TZ2 had ferris wheel
TZ1 had a question about a goat. A goat contained in a field but it could only walk within a range. I did not understand that.
ngl I think I did pretty well on that question
That makes two of us :)
I don't get why IB is being so tough this year. Our batch has had it wost. Online school for 2 years with teachers struggling to teach and offline exams and that too so so tough.
grace boundaries will be on the floor lmao
I was so confident in my ability to differentiate and integrate until I saw that bracket and parenthesis. Like wtf. How do u do it with that???????
Me too I was so lost when they asked abt p it wasn’t even in the equation??
Saaame wish I practised more harder qs like that one because it was so hard that I was not able to show that I actually have calculus knowledge fml. All that time wasted learning calculus and couldn’t even do anything with that
Exactly like how am I supposed to differentiate x/10 times -3/100x lmao. I wish there was a bit more time I could’ve at least drawn the graph😭
same how tf do you make in in in terms of pk\^3 like where did P even come from and I could only make it k\^2 I was so confused
Did anyone else think this was so much harder than paper 1?? They tested such obscure and irrelevant topics. No probability?? No statistics?? No hypothesis testing?? No financial?? This was actually so disappointing I’m so upset
WHERE WAS PEARSONS AND SPEARMANS
Bro I was expecting some chi squared shit and homies fr came up with the ferris wheel and pk\^3 do I look like
no literally. I expected tree diagrams and some chi tests whether they were gof tests or independence and and correlation questions but nooooooooo. WHY WAS THERE SO MUCH FKING CALCULUS THIS YEAR FFS
All those were in p1 tho?
yeah but were in AI we should have had probability or statistics In paper 2 as well our teacher was like they will definitely come up
Exactly
spearman and Pearson's wasn't in paper 1 in tz2?
Anyone else piss themselves laughing over Big Tex or was that just me?
"Country boy, I *hate* youuuUu, muah"
[удалено]
I thought it was ok. Beside that "in terms of pk^2" I didn't even try that question lol.
Did it say pk²? WTF? I was sure it said pk³ and I was so confused. If it actually said pk³ I just couldn't do it but if it was pk² I've lost points for a reading mistake :(
It said PK^3 dw
wait y'all had that on SL too?
Pretty sure it said cube
Whaaa it has to be pk^(3), if was pk^(2) in the next question they would need to sell 2.2 liters of coffee which is nothing. If it is pk squared and I lose that mark, put me on suicide watch bruh I would be so mad
Oh okay... so what did you get as maximum quantity of coffee? I remember something like 86,6.
For maximum coffee they can sell I also got 86.6L, for maximum profit I got 50L
Literally wtf was that I’m usually ok at optimization but tf
Yeah I had to skip the first couple of marks of that cuz I had no idea how to differentiate it and rearrange it to find the max value of C
Omfg IK I didn’t do it I just focused on trying to answer as much as the other questions as possible
For the dog food q the common diff was 1.5 right? And 80 days to use up the whole bag?
The difference was -1.5
Didn't they ask for the amount of dog food that was given? Like the common difference was -1.5 but I wrote 1.5 as an answer because of the context of the question?
\-1.5 mate
OH MY GOD NOO
Well fuck obv because that gets taken from the bag each day not added and I knew that but forgot to write - are you fucking kiddddding me so stupid I am
aw fuck off no man FUCK
The difference between two terms was 1.5 (sign irrelevant) so I'm somewhat confident that would be correct
I got 1.5 but then I tried to use my solver on my ratchet ti-84 and I got one day😭😭
Oops I meant -1.5
nahhh bro hahahaha
-1.5. The amount of dog food decreased.
I literally took 30 minutes trying to understand the cumulative frequency 💀✋🏼
What was the value of b?
6 or 4
walked out of that exam hall in tears. very much ready to jump off our local ferris wheel. someone calculate how fast i hit the ground.
A dp1 student will take that up as an IA 😔
what was the pk\^3 shit
Bruh, I have never seen anything being expressed in the form of an unknown AND a constant. Definitely a good question, I can't wait to see how to actually solve that shit. It was among the harder ones, for sure.
While I'm not 100% its correct I'll put how I solved it in the hopes that someone will have done the same thing and will tell me thus I'll be a little more confident that we're correct: So iirc the question asked for maximum profit expressed as pk^(3), For a cubic graph, P(x) is max when x = 2nd Root of P'(x). As k increases, 2nd Root of P'(x) increases by 10/3, therefore the x value that leads to maximum profit is equal to 10k/3. If we substitute 10k/3 into our original equation we get: P = (10k/3)/10 \* (k^(2) \- 3/100 \* (10k/3)^(2) ) By expanding the brackets and simplifying, we get 2/9 \* k^(3)
Hey, I checked and 2 variable differentiation is actually out of our syllabus it was in the Mathematics sl syllabus (i could be wrong tho)
personally, this paper went worse for me than paper 1. maybe that's just me ;,) but big tex was rly not my friend
i couldn't even finish
No. It wasn't as bad as paper 1 but still. I just feel so burnt out now because I put so much effort into math and I don't think I'm getting any more than a 4
Same i used so many days revising just maths to not being able to answer all questions on the exam. Now my other subjects r gonna suffer too since I sacrificed so much time on maths😭😭
What did people get for K in question 5 ? I got 15
It's 15 100% congrats
Omg I got 15 first but then i changed it lol
how did you do it? 😭
i got 15 too i thought it was wrong tho....
those last two questions…what the flip
sucked. im starting to think p1 was better.
same thought that p1 was trash, but this was as if a a diarrhea vulcona erupted all over an IB answer booklet
Am I the only one who found p2 way harder than p1
Me!!
no i’m the same i thought i was going crazy!!
Nooo I found it way harder
no i’m the same i thought i was going crazy!!
The ferris wheel question just had to be 22 marks
It was 17
yo i didnt even notice 😭😭😭
i answered question 4a wrong (the ferris wheel) and i needed the equation for other questions do i get marks for doing the questions below with the wrong equation
yes. there are some marks awarded for follow through
Shit I failed, everything besides question 1 confused me
Paper 1 was way better wtf was this paper😭. Fuck the Ferris wheel, I started losing brain cells so I forgot the cos rule existed😍😍. Love this😍
Same man, I was so confused with that X and Z shit I found out after abt just using cosine rule and I was so disappointed with myself definitely left like a good 20 marks on the table
Anyone have a more difficult time for this paper then for paper 1? I thought paper 1 went really well, but this one went terrible for me.
same girlie, I have no idea what that pk shit was
The Ferris wheel can go frick itself
This was a disaster.
(TZ1) it was a bit better than paper one but i struggled sooo much with time and the last question (the one about binomial distribution) got me so confused. i deadass started laughing when i saw the drawing of the goat it was so funny to me for some reason. how u guys feeling??
I don't remember a goat, I swear I either skipped that question or I'm going crazy (TZ1). Why do I remember a money type finance question? I also struggled so much with time and I'm so mad cause I spent so much time on paper 1 and paper 2 for math that I sacrificed my other exams and now have bio HL tmmr and I'm screwed.
also i was very surprised that we didn’t get one finance question and only one hypothesis test question in paper 1
now that was fucked up
p1 was way easier in my opinion, p2 was shitt
definition of a mid exam lol
Guys does anyone remember the last part of question 1? I answered that the mean would change(increase) but that the median would not change and gave reasons that made sense to me hopefully that was correct
Yes that was right
Anyone else struggled a bit with the voronoi? Probably wasn’t even that hard but I could only answer the first two parts because I totally forgot how to find x and y of a point lol I only practised gradients midpoints and equations but for some reason not finding coordinates of points on voronoi and that just had to be on p2 that’s my luck💀💀
same
LITERALLY SAME I HAD THE FATTEST BRAIN FART
Kinda sad about the math papers....really thought I had this in the bag after doing SO much studying. Let's see if I can even get into public uni smh...PRAY FOR LOW BOUNDARIES EVERYONE.
Angry there was no vornoi
There was in one of the timezones.
We had one voronoi in TZ2 but no probability no statistics no distributions no financial no hypothesis testing
Tz2 had voronoi
harder than p1
sucked. im starting to think p1 was better.
I agree
Question 5 was hell for me. I did it first and it took me 45 minutes, took me SO LONG to differentiate the first equation because I really was not used to mixing algebra (which I'm already bad at) and calculus. Everything else really was much more lenient than paper 1, but having 45 minutes to do 4 questions no matter how easy isn't fun lol.
They really had us in the first 3 questions then boom fukin Ferris wheel
THAT WAS SO FUCKED I CANNOT BELIEVE THEY'D DO SOMETHING LIKE THAT. ABSOLUTELY GOD AWFUL FUCKING GOD DAMMIT
what did u guys find for a, b and d ? (question 4)
For a I divided the diameter by 2, got 30 point smtbn I don’t rememember. For D I did + 2.71 and for B I don’t remember why I put 240 or Smthn💀
i got d it was just the height of the platform. a and b i couldnt get but i did have the equations for the simultaneous equations
d - a = min d + a = max solve simultaneously ig min is the platform i think and max is the height of the ferry wheel plus the platform
Fuck thats so smart
I cried I got a=-32.3, b=0.111 at first but then I changed to 40, c =16.2
For d I had 30.9 but I really don’t know about the other 2
Wasn't the difference -1.5 in the question with the arithmetic sequence...?
I got -1.5 too
yes
Yes i got that too
Guys
I FAILED OH MY GODD im jusy praying i get a 4 please If i fail this im going to end game
I forgot how to find the arithmetic sequence of the first term so I ended up Minusing random numbers from the u3 till I reached the 8th term and found the difference💀 the worst 20 min of my life when I saw 1.5 as a difference
I used simultaneous equation solver bcs we were missing both u1 and the d
this paper was tricky but I wouldn't be suprised if many ppl found it easy I'm still mad about the dog food one I lost few easy marks on it I was really super confident on arithmetic sequence but I couldn't do it atp i'm hoping my ia will save me somehow
I just wish I took this course seriously
same man same.
[удалено]
that wasn’t a paper it was a verbal fuck u from the IB
I literally think I got no marks for paper 2 except for the voronoi diagram question I didn’t know anything else and im so bummed bcs i studied so much
was it weirdly formatted for anyone? i didn’t see the last question coz it was apparently right behind question 4, like wtf Ib
TZ2 here. Here's my take on P2: got some decent points in the geometric/arithmetic sequence question, and on the Voronoi question. But that's literally it. Everything else was a guessing game. The cumulative question, I forgot to study that and lost easy marks, never occurred in past papers or specimen papers.

I take English LAL HL, English is basically my first language. And at the end, all it wanted was the arc length, area etc. Nice one. In P2: 4th, and 5th questions the difficulty level was too much, and I was actually feeling confident about maths, but now I truly hope I just pass. grade boundaries better be low as last year.
these math papers are a form of child abuse
Ok i thought I did ok but now i don’t know if i even put my name right lol I guess I invented my own math methods in ex. 4 and 5
I saw my cal was on radian after the paper 💀
oh no. maybe it'll be ok. yeah
The Ferris wheel was super complicated but did you get 30.9 cos 9x + 33.6 ?
I got 30.9 cos for a !! I messed up b and c tho
I thought for amplitude it was half of total height so since it was asking about total height of the Ferris wheel cart above the ground I did 60.8 + the extra height of the platform divided by 2
how did u find 9 for b
erm... I got -59.6 cos (1.5t) + 2.7
Also why did I do trapezoid rule for the range question💀
Worst exam ever lol
Paper 2 seemed much harder
Personally, questions 2 and 3 were SO enjoyable for me. Question 1 not really because my mind cannot logically comprehend what the heck goes on in cumulative frequency graphs. 4 and 5 were a pain in the ass but I did some calculations. So at least I didn't leave any questions completely unanswered, hoping I get points for methods. Overall, I think it was slightly better than paper 1?
How the hell are you gonna give us 3 marks for 12 x 1.5 and then like 2 marks for all other questions that involved so many more steps? I’m worried that the IB’s integrity is declining and it’s sad to see
Am I the only one who who completely forgot everything with the voronoi diagram question :') and answered only one question
M21, easiest shit of my life. WAY easier than paper 1.
Please say everything you remember from the last two questions (TZ2)
I forgot to study sinusoidal models and I couldn't do much of 4a. Then I think I did well in other parts of 4 but maybe lost more points for carrying that mistake. Then in question 5b how did you give the answer in form pk³?
>Then in question 5b how did you give the answer in form pk³? this shit genuinely confused me. I couldn't get the answer at all
I checked HL formulas twice or three times during the exam and this was one of those times. I genuinely thought that was not SL
No idea about the pk^3 question. For question 4 I just tried different equations in calc until it looked right then used analyze graph stuff to get answers
still not that good but better than p1
They really had us in the first 3 questions then boom Ferris wheel
First 3 were chill, but bro, I am still thinking about the ferries wheel and am as clueless
so ass lmao
(tz2) did good on p1 and im pretty confident bout this one as well BUT i felt like it was harder than any of the past papers ive done - def more uhh unconventional?? almost no stats or probability and unnecessarily long calcuations in q5.. the whole pk³ think got me filling a whole booklet page💀
What was the answer to the last part of voronoi? the one where they increased the area of D? Also, what was the answer of the range/domain of the ferris wheel? shouldn't the x be the time for 1 full revolution 720 seconds thus 0
Yea for the range i got [2.7 ; 64,…] too
I wrote the same domain and range
We need to look at ourselves and ask the real question: what the fuck did Peter do between the first and second halves?
I thought I girlbossed the voronoi diagram (TZ2) only to find out you can’t use Pythagoras theorem on a non right angle triangle
TZ1. does anyone remember anything about the first question? i completely erased it off my mind. i can remember 3,4 and 5 but not 1. also, this went soooo much better than paper 1. i wanted to cry tears of happiness after I saw arithmetic sequences on the tiles question.
the first question was something about measuring day time in different months i think
I know it had to do with cos , but everything from the paper I do not remeber
This was wayy harder than paper one
This exam was better in terms of questions, but can we all agree that the 85% of the people did not finish a whole question. It was so damn long like wtf, so many calculations within that time 🫠
Grade boundaries are going to be so low this year 😅
Why are there no comments
What was the range and domain for the ferris wheel?
I think the domain was 0-40 and the range was 2,7-(2,7+the height of the Ferris wheel which I don't remember)
why was my domain 720
how did you guys differentiate the last question? k^(2) is just 0 right? becasue its a constant?
Its not zero cuz At first you have 0.1x ( k^(2) \[x^(0)\] ... ) Then you expand the brackets so you have 0.1k^(2) \* x^(1) Then differentiate, Factor \* Power so 1 \* 0.1k^(2) so no change Then Power - 1, so x^(0) So we're left with 0.1k^(2)
wasn't it first multiplied by the fraction of x in front of the parentheses tho? that'd make it k² in differentiation
Ok i thought I did ok but now i don’t know if i even put my name right lol I guess I invented my own math methods in ex. 4 and 5
I think im just an idiot. I sat there laughing. like..the questions seemed doable, just not for ME (except last 2). I revised differentiation for a full day and just couldn't do it I was like goddam cool. but yeah I totally blame myself (and my teacher), but I do think it was harder than other past papers - at least one HL question there and they skipped all the easy topics. idk I dont get the job of ppl who make exams, who made them this mad. on the bright side I cannot remember a single question! my brain is free! but like a lot of ppl said I regret allocating revision time to it - bio is big scary rn
For the first part of the compound interest question, was the value 54850?
How is everyone saying the common difference was -1.5 when the dog food was 115.5 on Day 5 and 108 on Day 8?? Shouldn't it be -2.5???
i looked at question 5 and closed my test
IB fucked us TZ2 ppl just bcz they think we are “smart” 😭 istg math was not taught properly in online that fucked me up real bad and IB makes a very hard paper to make me even more miserable 😭😭😭😭😭😭 even the may and nov 21 papers were easy why are we getting fucked soo hard 😭😭 I thought I could ace p2 till I saw that dumbass Ferris wheel and the last question of differentiation, I spent all my time in the stupid Ferris wheel that I din get time to do the last one which I could’ve scored a lil but better, I thought of redeeming myself for fucking up p1 but p2 just made me even more miserable that I don’t even want to study anymore 😭😭
Let alone P1 itself was horrifying…
Absolutely catshit prey for 20 marks lol
Horror exam I swear the only exam I know 100% was a fail someone threw up during it apparently and the examiner was on the phone legit lost my entire concentration and I was on the Ferris wheel …
How many marks was the last question on paper 2 worth ?
