Not bad at all, one or two things I'm unsure about, notably the integration of the 3^2x term...did anyone end up with some multiple of pi divided by some ln3 term as the final volume?

I kept getting e^1/4sin2t at the bottom of my differential eqn How were you supposed to get e^1/2sin2t? I got the 6 and the 3 so I have no idea where I went wrong.

For the last Q I got:

(26pi-108(pi)ln(3)+27)/ln(3)

I have no idea if that's right lol, anyone got something similar ?

I don't think so but don't you lose an accuracy mark if your final answer has an unsimplified fraction in it?

I think I did pretty well! Feel more confident in this than C3... I was abit too stresse out and sleep deprived for C3 so that may be why I messed up...

But I think I did pretty well.... That is until Arsey releases his markscheme LOL
