I'm going to cry because I just realised that I made a stupid mistake in the volume question by using the auxiliary angle for finding the intersection... even tho I did all the integration correct, because I wasn't thinking I'm now gonna lose like 3 marks RIP..
how many marks do u guys think I'll probably lose for that?

thank u, im convinced it's the universe trying to make up for me being the only one in my class feeling like crap after ext2
i've got friends that do ext2 and their feedback was much or less the same. They said it was torturous. so dont worry too much

Doubt they'll lose anything more than 1 mark, unless there are subsequent errors

Vectors and differential equations were my favourite topics, so I'm sad they didn't include more of it, except a simple dot product question and circle with radius 1 differential. I'm glad the only stat was empirical rule though.

Will i get any marks for my volume integration one? I got the right bounds but wrote it as (cos(2x) - sin(x))^2.
