This didn't go too well for me, I could've done a lot better if I'd thought more about the order to attempt questions in. I'd appreciate someones opinions on how many marks I will have picked up.
Q3 - Full apart from didn't realise they required justification for the last part, I did leave an explanation for even n but I don't think it was very good, and I assumed for odd n it was obvious enough from a sketch.
Q5 - Full
Q6 - Did eveything up until the last part, where I got a differential equation for v but I didn't solve it
Q7 - (I should've attempted this way earlier instead of in the last couple of minutes) did the first bit and the first integral but then ran out of time.
Q8 - Did everything from the start and showed the first approximation then skipped to showing the error term and then wrote down some stuff on the way to doing the last bit but didn't get an answer.
reckon this might scrape a 2?
