I thought this was a hard paper; I got most of the questions but I've made really ridiculously stupid mistakes. eg on question 7 when I differentiated I must have done it wrong someone as I got a different cubic to everybody else, this therefore made my answers to the next part wrong even though I used the right method. on question 1 I left part c as 1-tan theta over tan theta +1 and didn't sub p back in. But I got the trig proof and the last question I think. annoying.

i know no one can really tell me how many marks I'll lose - but for 5b I made a sign error and got 1/8pi rather than 1/24pi, leading to me getting the coordinates as the origin. I did (4-2) rather than (4-(-2)), but i differentiated correctly and did everything correctly after that mistake - anyone want to suggest how many marks out of 6 I'll get?

For question 3, you're meant to put k>2root5 and k<-2root5 right?
Yes you are sorry I didn't write that

Let me be the first to say i was very "well prepared" for this paper and still struggled.
Granted im thinking i failed 8a) (after an hour invested and 5 seperate methods, i still didnt get much further than 3 steps in, knew i shouldve taken RHS...) due to calculation errors early on, id still estimate at least another 3-4marks lost elsewhere. Just to clarify i got full marks in June 13 when i tried it, id admit it probably was a harder paper than this years but still. This was not an impossible paper, but it was certainly not "easy or very easy".
For those that would suggest otherwise congrats on getting a paper you could do without difficulty, just please stop being condescending arses, it doesnt impress anyone and just serves to piss people like me off :/

Would you get 2 marks for saying f(x) is increasing because as x tends towards infinity, f(x) tends towards 1?
