    4cos^2x - cosx = k
    Yeah that's what I got, but is that really the answer. I was confused because that seems more like k in terms of cos x than cos k in terms of k...

    Not sure how people can say it's 'a really easy paper' was definitely harder than any mock I had done and got high A's in the mocks, feel like this was a B, the questions definitely were harder in general

    checked with my friends and decide to put these down before I forget... :llama:

    - a= -48, b = -96 (might have mixed them up, can't remember)
    - Factorise f(x) = 3(2x+1)(x-4)(x+4)
    - common ratio: 8/9, first term = 18, n = 28
    - Area of graph = 226 sq. units
    - Perimeter = 40.9 cm; Area = 96.7 cm^2
    - the minimum cost for the cylinder is 483 pounds
    - Angles from tan: pi/9, 4pi/9, 7pi/9; angles from cos: 0. 139, 221 (3 s.f.)

    Hope they are correct! Waiting for Arsey's unofficial mark scheme though hahahaaa

    You had to sub r = 2.92.. back in to find the actual cost

    You have to add the integrated areas separately which adds up to 226
