    I thought that tanx=root 3 as pi(n) +pi/3 are the only possible general solution for it and as tanx had a period of pi you always get root 3. And you matrices question seemed fine as cos/sine have periods of 360 degrees so cos(-60)=cos(300) same for sine
    Ahhh actually I think I got root 3!!!
    I'm getting mixed up with questions lol
    I'm all confused

    I can't remember exactly :/ But there was an equation with " i + qi " in it and it asked to explain why q must be -1 for it to be real
    Basically as the roots were conjugate pairs the cofficent a are all real so the imaginary need to cancel out and only possible real solution for q would be -1

    Oh, right... I put that imaginary parts had to cancel, would I get a mark for that? Not sure what the other mark is for, stating the roots were conjugate pairs?

    How many marks was the part b) of the trigonometry question)

    And anyone remember what their inequalities were for question 9 last part?

    Both were a pain in the ass. Lots of people got them wrong so don't worry.

    No the one with the parabola where you had to find possible k values.

    Here is what I can remember. Someone make an unofficial mark scheme.
    I need to focus on M1 & M2 now. I can't dwell on this.
    arkhglsigh its going to drive me crazy...

    Roots of quadratic equations
    2x^2 + 6x + 3 = 0 ??
    alpha + beta= alphabeta=
    Roots are alpha/beta & beta/alpha,
    Find a quadratic equation with integer coefficients [5 marks]
    7x^2 -4x + 7 =0

    Linear laws
    (a) y=a(b^x)so logy=loga + logb^xlogy=loga + xlogb
    You are given that Y= logy and they gave us the graph of Y against x
    With the intercept being 2.25??
    (b) gradient is -0.4?? I've forgot :/
    (i) Values of a & b to 3sf
    a is 10^intercept,
    b is 10^grad,

    General solutions to trigonometric equations
    (a) If sin(pi/3) = cos (x/k), find k, k=6 [1 mark]
    (b) Find general solution to cos(2x - pi/2) = sin(pi/3) ??
    Ended up getting npi + pi/2 and npi + pi/3 ??
    (c) Hence find the only finite value for tanx [2 marks]
    Can't be pi/2 as tan(90) gives an infinite valueSo pi/3 therefore
    tan(60)=root 3

    Matrices

    Find other values for q
    Q= -12i-1 and 4i-1

    Parabola y^2=4ax, given that it is translated by [2,3] and passes (4,7) ??

    Yes !! I think I got the same as you except I flopped the tan question cause I didn't understand what it was asking at the time but I got the same coordinates for p and the same equation for q.
