    I found it jolly easy, to be honest. I actually requested a harder paper, but alas, my wishes were not fulfilled. Remember: una salus victis nullam sperare salutem.

    Grades boundaries are staying constant. 64 for a A

    No they're not... Exam Boards work out the average mark and consider loads of statistics before deciding on a boundary they would not just stay constant. Plus May 2014 was 60 for an A so

    Attachment 403327403331 Hope you can see this picture on how the solution to how to write cos(x) in terms of k.
    Pretty sure i got 100% in that paper but trust me when I tell you that's one of the hardest C2 papers I've seen, and I've done them all
    thats wrong u dropped a 4

    did anyone get d2C/dr2=60pi? in addition, how much would I get for that GS question I've put a=45 instead of a=42 and ended up getting n=17

    Hi there, I got to the point of forming the quadratic using the identities but then I didnt solve it correctly, do you think I would get 2/3 or only 1/3 for forming the quadratic (I completed the square instead of formula lol)

    I believe there were more solutions to the tan equation? It was up to 2pi?

    Didn't anyone else just set 4cos^x + cosx = 4-k and then factorise the LHS?

    Same. Just that I didn't take 3 put of the bracket. Feeling regret a little bit now
    For the factorise one I got

    (2x+1)(3x-12)(x+4)

    instead of

    3(2x+1)(x-4)(x+4)

    I remember d2C/dr2 is something like 12pi + 600pi(r^-3) :colondollar:

    is it cosx=k and cosx=(k+1)/4????

    I only got x=0 for part C
    I got this too!! I'm pretty sure it's wrong though
