For 4 (b) you seem to have got confused with the brackets. Unless my eyes deceive me, the first term you are differentiating is f(exp(x) v(x)), but you seem to have thought it was f(exp(x) v(x) + 2x - v(x)^2).
To be honest, I can't be bothered looking at Q5; they look like they'll be fairly tedious, and it's late! It would help if you posted your workings, then we could check those, rather than having to do the whole question ourseleves simply to check your answer.
