    well I changed to sin in cos x tan and then factorised out cos to get
    cos(3theta)(tan(3theta -root3)=0
    then i did tan(3theta)= root3
    and cos(3theta)=0 and i got 6 solutions in total.
    There was only 3 mate 0<x<180

    I reckon 62 for an A, if I'm honest it wasn't much harder then the other edexcel papers I've done, the only difference being that you're sitting in an exam hall a fairly stressful environment, not in the comfort of your own home, so its likely people are going to make silly mistakes.

    But going from that, i really can't see it being lower then 61 for an A, nor can I see it being higher then 64 for an A...
    But who knows aye...

    You got the last one wrong as it does not cost £3 for a whole clean (common sense) but you sub 2.92 which was r back into the equation to get the whole cost which was C!
    harder than a solomon paper? lol are they having a laugh?

    The range was from 0=x<360...
    Yeah within the range mate. Inverse tan root 3. Don't u get a positive and negative for square root?

    How did people solve

    sin(3theta)-(Sqrt3)cos(3theta)=0 0=theta<pi

    ??
    For this question I think many people have got wrong.

    From Sin x / Cos x = tan x

    We can get sin x = cos x tan x

    Therefore cos3xtan3x -root3 cos3x = 0

    Cos 3x ( tan 3x - root 3) = 0

    ...And solve

    So here is my answer
    Q1: 1024-1280x+720x square
    Q2: (x-2) square -(y+1) square= 20
    Part b i got gradient =1/2, x-2y-14=0
    Q3: A=-96,B=-48
    Fractorise =3(x-4)(x+4)(2x+1)
    Q4:40.9 perimeter and 96.7 area
    Q5: r=8/9,a=18,n=28
    Q6=32+194=226
    Q7:y=1/3 or y=3/2
    Q8i/9,4pi/9,7pi/9
    Cosx=1+/- square root of (1+16k) devided by 8
    X=0, x=136.8 or 138.6 something,x=221.4
    Q9: 483
    On question 5 I got r=(85/126)^1/2 or somewhere around there that was very close to but not exactly 8/9 and when I put it back in to find a it gave me 17.988 so I rounded up would I get the marks?
