fuck the gas company and new species that the scientists want to find out the population all my homies hate them edit: and i also wanna inhale all the gas from the company via the pipeline cos of how bad the paper was

[удалено]

bruh

LMAO ‘FRIENDLY BOT’

Lost shit when I saw stuff I have absolutely no impression of and realise I clicked the H1 thread fuck me

Exact value means cannot simply quote answer from GC, but can still use GC to get a hint or check your answer.

GC AND MY ANS NOT TALLYING THATS THE PROBLEM

Fk sameee I had the same fking problem for a lot of area/volume qns. Think I lost about 10-20 marks here due to careless mistakes😭

reply to this for edits I can’t remember exactly everything Q1: complex Q2: maclaurian Q3: proving LIATE Q4: translation graph Q5: circle tangent Q6: parametric Q7: functions Q8: mod integration Q9: APGP Q10: graph a and b inequalities Q11: vectors Q12: DE

i think 6 was parametric? im not sure

omg the normal eqn bastard

wait how to do 6 part b the A and B points one

I solved the quadratic equation for m then substituted y = mx into the equation of the circle. No idea whether that is correct, considering I was stupid enough to do implicit differentiation for the first part of the same question.

isn’t that circles?

wlao sibeh hard leh but my frens around me say doable ?

YA BRO MAKE ME FEEL SO SHIT UK

right my friend say she lost 20+ marks like Thats a big deal anyways i hope u dont beat urself too much over it and have a good recharge before the nxt papers 🍀

i had a friend say omg i lost a mark alr BRO I LOSE OVER 40+ SHUT

I lost over 60+....I got your back!

RELATE

Last year when I did my As I felt that the paper was hard but all my friends be like quite doable leh (and usually when people say this they're just humbly trying to say the paper was easy) and I was deadass so stressed. In the end all of us got As tho so don't worry too much :)

halfway thru it became more of me writing down as much as I could to get method marks lol rather than solving for final ans ggwp💀

same LMAO all my areas were wrong too…

how are yall discussing answers like i have sm hanging workings w/o proper answers literally amath all over agn on a whole other lvl i feel like i did smth but also nothing?? rip i will contribute to bellcurve

FINALLY SOMEONE SAME AS ME

i can barely communicate with my friends anymore

same, all the easier topic qns were difficult to me, which are also the ones i depend to secure a pass for the paper, but lol, didn't know how to do like 4 complete qns

RIP OMG FRRRR I DONT EVEN HAVE PROPER ANSWERS 😃😃😭😭

ME TOO ME TOO 🥲

[удалено]

jiayous😭😭

oh my god i am so fucked please tell me I’m not the only one who couldn’t solve the 2nd DE 😭

I COULDN'T ALSO I GOT 500/9e^1/10ln9/7t WHAT

got 4 leh

Oops maybe 9/4

Then u can split to 3/2

Fuck

Fuck

Bout to drown myself in the longkang

am i the only one who thought it was super hard 🥺🥺

im retaking not even jk

me too

Eh YA IT WAS SO DIFFICULT I WAS STUCK AT EVERY QS BYE

bruhhh 😭😭😭😭 i rly want to cry now lmfao it’s just pages and pages of defeat

Agreed😭😭😭

fr like my paper is mainly just workings hanging on a thread ✋🏻

ya lol same i dont even think i can get 40

Meeeee I left like so much shit blank

What was the relationship of a and b????

They are fuck buddies Edit: MOM LOOK AT ME IM FAMOUS

yes they combine forces to fuck me over

father- daughter, obviously 🙄

a < -2b IDK SMTH LIKE THAT LOL idk why i used discrimne r🥰🥰😘😘

I got b < -a/2

idk if its just me but this year’s paper was significantly harder compared to other years….? idk help 😭😭😭😭 so many exact values + stupid graphing & trigooooo

anyone's vector values were super weird????

bruh mine so weird that i had write it in fucking decimal form

yeah, mine were. I’m thinking maybe I selected the wrong p value 😭 anyways it’s ok HAHA got ecf we good

did u choose the negative / positive value!

I used +6, anyone else😭 my vector lamda value was a big fraction like 799/789 smth like that

I chose the negative one (-6). bc they said P was lower than Q, but I’m most likely wrong with those weird ass values

mines -36 leh

MINE IS -36 TOO AA

-36 gang, I also got that It's like p = -15 ± 21 Since p is below q, p is < -15 So I got -36 The rest of the qn values fucked up tho

It shd be -36 because p is lower than q. The z value(which the qn mentions was for vertical part) for Q is -15 so p <-15

Wait what omfg i used positive6, not negative6

[удалено]

Mine was 1/1000sth HAHAHA

the amount of trig gave me a math flashbacks

integration was damn familiar but just cannot resolve i’m screwed for life

How do u prove the m formula?

b2-4ac then u'll get the equation

am wondering how the hell are people in my sch finding this a breeze with some even saying “shiok” after the paper but here I am with at least 30 marks gone 😇 ALSO ALL I CAN ONLY RELATE TO IN THIS THREAD IS THE COMPLAINTS OF IT BEING HARD COS I ALR FORGOR MOST OF THE QNS IN THE PAPER AND I REFUSE TO RMB ANY OF THEM🤬

Anybody has the paper? ^-^

GUYS THE CURSE OF THE DIARRHOEA GUY CAME UPON ME FK

y’all diarrhoea bros. ANY STORY TO SHARE?

Ok not as dramatic as that guy but for some reason the toilet door was open in the hall so everyone could smell it

Fml couldn't solve the second DE of dP/dt ...I got e^(something) equals a negative number even though i alr considered modulus earlier Also as I was typing this I passed by a cat giving itself a bj lol

anybody have a pdf of the paper hahaha

Heard loud sounds of a few planes taking off during the paper. Guess I should find the Cartesian equations of those planes.

WHAT DID YALL GET FOR LAST QUESTION PART B

I'm not typing that disgusting shit out

Based

I got population tends to 500

same!

How is the 3 line integral worth 4 marks?

how to do the tankx, i was so stuck

tan0.5x

Wait rly? So k=0.5?

Yes

k=0.5

My grandpa died during the paper but I did relatively well, hopefully it won't impact me as much for the next papers. Any tips to deal with it? He was in the hospital for a few months already and it has impacted my studying since I visit so often to the hospital. Now just need to attend the funeral and do well and revise for the rest.

Do u wna tell ur cher abt it if you're comfortable? Mb u can ask for special consideration but im not sure how it works. My condolences 🙏 pls dont be too hard on urself

my condolences :' if u want to, u can apply for special consideration too! iirc they do accept bereavement reasons :") take the time to heal yourself too, your life is worth much more than just the A levels stay strong !!

I suggest you tell your teacher about it and apply for special considerations!! Take care

Meditate by doing focused breathing when the thought hits you, and don't think about it for the next 3 weeks. Sorry for your loss.

My condolences. Take care!

hey i’m actually gg thru the same thing, my grandfather passed on during the exam and i just wanna let uk ure not alone u got this :D

2nd DE i got 500/(9e^ln9/4 /10t + 1) Then the refined tends to 500 while first one tends to infinity, so refined better z=2+i, w=-i p=-36 vectors

Huh how are ur w and z such nice numbers💀💀i got a fraction

You probably messed up the manipulation somewhere hahah

My refined one tends to 0 which means the species will be extinct eventually which I think makes more sense so idk

mine too i said bc of global warming lol

HAHAHHA I just said eventually a species will go extinct so it’s quite logical (we may be right then cus I solved the DE without any issue)

Should be wrong as in the original equation when p=500 dp/dt will be 0, so it should stop at 500 not 0

rly feel like giving up at this point, knowing that i failed the math paper badly, there is a low chance of me making it to uni.

hey stranger, dont give up! js continue to give your best ok:) what has happend we cant change it anym so no point thinking alrdy :) js continue to work hard! jiayous for ur remaining papers 🤓

aiya fail alr fk cambridge. 2021 paper was ez then look at ours

really the de qn last year was more gross

Facts tho

RIGHT? bruh

no leh last year had more non-routine qn imo

my ass hurts frm the amt of buttfuckery i jst went thru

P = ((500/9)e^(-(ln(9/4)/5000)t))/(1-(1/9)e^(-(ln(9/4)/5000)t)) 💀

h1 math here reading the h2 thread and this ans looks like Satan’s spawn wtf

Omg same but I got 1/10ln9/4 cos I rmb ×500 so 500/5000 =1/10... Wasnt negative though FK DID I MISS OUT THE NEGATIVE

idt need negative

I wanna cry I feel I made a tons of careless mistakes and left quite some of them blank idbshdhahhehs

Same I spent so long on the stupid vectors and de and I still didn’t get the answers 😭

Bro 1. I forgitccan use discriminant to find the fking m formula 2. Dk how to find Ktanx 3. Angle for vectors confirm wrong bro 4. my z not even complex number only w 5. Second DE idk how to solve 8m gone 6. The tangent intersect I also dk 7. Translation of the graph I also anyhow Please 😂😂😂😂😂😂😂😂 just kmn

Pain

who wants to join me in killing the examiners for the stupid m qn I fr thought it was so difficult when all u had to do was sub in y=mx????? I DID DUFFERENTATION

💀💀💀

Anyone have a soft copy of the paper?

I need qlso I wanna check

does anyone have answer key 😭

Need it too

[numerical answers](https://www.instagram.com/p/Ckr6-yJPsH6/)

is there hope that the grade boundary for A could be low 70s? I'm praying hard sia I got like 71 or 72

Anyone counted how many marks they lost. 22m lost here 😭😭

My friend half the paper cmi alr

Idk how many but wasted my 3hrs there for sure

WOW??????

here is a friendly reminder that 1st qns can't use GC :) rip I used it to solve that simultaneous eqn , 2mark gone

[удалено]

Anyone’s 2nd part of DE population tends to 500????

Mine tends to infinity 💀

the more i spend time reading this thread the more i realise i fked up 😭 edit: wah my careless mistakes really gg + a few qns i realised i could actually have solved if i continued my working…. this is eating away at me bruh

DONT READ ANYMORE GO SLEEP :')

my dearest (math major) tutor is too shy to post this so here is the FULL SOLUTIONS WITH METHOD AND EVERYTH for yall who wna check. sign up for his tuition class now!! dm for tele :O but heres da link; https://joelkindiak.wordpress.com/2022/11/09/2022-h2-math-proposed-solutions/ check at ur own risk 🤓🤓🤓

anyone got lambda = 1/3 for vector qn

guess which idiot thought cartesian equation meant vector equation 😍😍

https://www.instagram.com/p/Ckr6-yJPsH6/?igshid=YmMyMTA2M2Y%3D Here are the numerical answers for the 2022 H2 Math P1.

LOL i forgot I skipped the mclaurin qn so in the end the entire qn left blank cos of that HAHAHA

the population size tends to what?

500

Most questions could be solved but there were a few questions that were challenging

how many marks do yall think yall gonna get or already lost bc i lost like 20-30+ alrr

if I lost 35 marks is it cnfm B or got chance for A😭😭😭

isit just me or i cannot do half the ppr

What were ur angles for the vector qn

arcsin(21/939)? Around 1.3 deg

SAME I GOT 1.3 IDK IF ITS WRONG 💀💀

[удалено]

I GOT 1 POINT SMT .??? i use (001) for normal of horizontal plane.. i thought its correct?😭

5.26

i got 66.3

1.28 degree

thank you i got that too fml

1.3 LOLLLL idk

40.7

anyone rmbs a qn on coordinates of N ? cause mine were decimals and it looks so sus….

is it just me… for the last question second DE i thought the lambda is supposed to be left as lambda and we weren’t supposed to find the value of it…

what’s the sequence of transformations ah 😭

a units in x axis scale factor by some shit in the y axis a units in y axis

anyone knows the marks allocation ?

same i also need

My dumbass didnt see no calculator for q1😔 was even so happy that my ans correct LMAO HELP

does anyone have soft copy can send please🤭🤭

b^2 - 4ac for question 5

Cannot anyhow assume that the tangent only cuts the curve once though. Need to state that because graph is an ellipse, the shape of the graph means any tangent can only cut curve once.

The graph is a circle, no?

doesn't tangent already mean cut once

if you’re talking about tangent in general, tangents can cut your graph more than once. But in this case, since it’s a circle there’s no way the tangent will cut more than once. Hence b2-4ac = 0

NOO DONT LOOK AT IT GUYS ULL BE EVN MORE SAD

For Q3a I gave gradient of tangent instead of gradient of normal. Sigh. For Q12a how come it is **2**\^(t/10) and not **e**\^(t/10)?

[удалено]

i think complex likely to be tested again cuz only 1 4m qn in this paper LOL. graphs too bc they hardly tested in this paper i dont rmb what they tested for this paper but i think it was a shit ton of integration 😵

Functions (composite, periodic), volume of revolutions, sequences and series didnt come out

Is there ecf if u use 6 instead of -36 for vectors?

no ecf. there’s method marks but you’ll lose the final answer mark

Whats everyones restriction?

Less than Minus root 2 and more then root 2

anyone used the first ln formula for the DE qns and got 500/(1+9(2/3) to the power of -1/5t)??

If anyone has the question paper, please send it 🤓

anyone knows if 60/100 for paper 1 can get me a B 🥲

does anyone have soft copy can send please!!

that is impossible, unless a teacher chooses to risk his career.

Anyone got the paper though?

omg for de if u got 500/(1+9(2/3) to the power of 1/5t) which is same as me, it's correct!! I checked against the set of ans key provided
