Was quite a fair paper I think. A couple of difficult questions but not bad

Yeah I got part a as a = 8 but part B for the intersection of the planes I didn't know how to answer that.

For the calcuating the angle question I pretty much guessed the angle as 137 deg (which isn't acute but whatever) using cos theta = a.b/|a||b| and a and b as the normals to the planes. I'm terrible at vectors and lines. What did you get for the integration by substitution question (2sin^4(x)cos(x) between pi/2 and pi/6)? Iirc I got 31/80 which made me think I made a mistake.

Yeah I got 31/80 for that question as well. And if I remember correctly I got - 33 for a.b and root 6 and 3 root 38 for the magnitude of the normals.

Same - I’m sure that’s right

its not letting me upload any pictures :/

Do you think the boundaries will be kept at the intended percentages? 70-A 60-B 50-C.

Looking back at the paper outside an exam setting, ive done so many careless mistakes.

Upload it to some image-sharing website (imgur for example) and try posting the link in the comments, might work.
