what did everyone get for that integration question with k? i got 1/0.1pi+1 or something

i got that

Really not good! What do you think about the grade boundary?

Oh okay nice, that makes me feel a I'm bit more confident, Ive heard a few people say they got this as well now, It just doesnt seem right tho

I mean at worst you pick up method marks , so you should be fine. I reckon it is 52 though.

i got that

Did you have to integrate sin^3(x), Because I ended up getting that as one of the things I had to integrate and forgot how to do it

How tf did you find k on that acceleration question

Original post by Aidantm17

Anyone get like -1.19 for question 1? I was stressing when I opened the paper and was struggling with it lol but eventuall i got an answer

Weren't you supposed to leave it in log form. I got that but as a log.

There were so many quiestions with K in lol i dont even remeber which one was which anymore

Anyone remember what they got for exact value of theta??

I cant remember I thought it said to 3s.f but i might be wrong

any thoughts on grade boundaries for this paper and the previous 2 ?

My mates got 5pi/6 which seems reasonable. I got (tan^-1(-root3/7)+pi which is 1000000000% wrong lmao

I got that too lmao i did u4 - u3 = 2(u3 - u1)

No because it said to 3 sig fig

No trust it was 2/3root6. Take it from me. An A* predicted candidate.

Genuinely hoping its in the 40s somewhere for an A lol, its been that low before and this was a tough paper. The other two it will be much higher.

Hopefully A will be around 150 in total again but it will probably be higher after paper 1 and 2. But tbh, i really dont know how to predict grade boundaries so probabale dont listen to me

He’s deffo wrong too

Wait the 5pi/6 or the one with tan XD

what did you guys get for greatest possible value of tan(theta) in the mechanics section?

Also was anyone else fuming that it said use g=-10, my stupid ass did the whole question with 9.8 and then had to do it again lmao
