DANG BRO HOW DID YOU KNOW

 

[potpal]

guys is there a chance i can make an e4 with a 64 raw

 

[WeiWeiMan]

Maths is stupid

 

[Dontcallmedude]

Funnily I did well on the topics I thought I'd do bad and vice versa

 

[HazzRat]

constant of integration, obvious i fear

I’m crying that I couldn’t get that question . I wrote some bs working out like the integration by parts was wrong or smthn.

I dont think so it seems this exam was a little easier than the last 2 yrs where a 64 could've

 

[HazzRat]

Where do u think the b6 cutoff will be? Maybe 70-75?

 

[Lachlan is the best]

Did anyone else get t=1/k for the last question?

Same and now I realise I’m so annoyed

My mate and I also wrote this… but one of them was doubting it so I just wanted to check what other people did. It really couldn’t have been anything else. Hopefully you went well for the rest of it.

Is Q8 even in syllabus? Knowing that exp(x+iy) = exp(x)exp(iy) surely isnt in the scope of 4u. I’m sure most 4u students have discovered exp(z)^n = exp(nz) doesn’t always hold true for non integers (hence demoivres only being true for integers) so to expect them to know the addition of exponents does always hold true in complex field is a bit iffy.

just use elimination to arrive at A for q8
