OCR A Further Maths Pure 1 25th May 2022 Unofficial Mark Scheme

I couldn't find anybody bothering online so I decided I may as well. It's only partially complete, only having the answers to the questions my friends and I could remember. If anyone remembers any other questions, or finds a mistake in something I wrote lmk.

1) Rotation around X axis (between 0 and 2ln3) for √sinx
2) Matrices q: (2 0 1) and (1 0 p) (vertically)
6?) Prove by induction that for -xcosx,
d^(n-1)y/dx^(n-1) = xsinx (n-1)cosx for n≥1 (something similar to that)

I believe the first one was actually for √sinhx but thanks. Do you remember the question numbers for the questions I've already put on there? Also what were the sub parts of q2? We had to multiply the matrices together both ways round, and I remember having to state that matrix multiplication is not commutative but what else was there I think there were more parts to it.

Do you still remember the distribution of marks for each question?
