7 was the 1st and 2nd differential of tan 4x.
I got P = 4 for the first one.
But didnt know about the second one (5mk question) though I played around with the identities, so I'm hoping I'll get some method marks.
I got stuck on 1a differential for a while ! :frown:
Overall good though I think.

7 b) q=32

8 b) i got 1/16 (((2x-2)^2)+ln(2x-1)) +c Maybe
