    My answers' other than show that questions:

    1) a) a+b = -3, ab = 7/2
    b) 4x^2 + 45 = 0
    c) a^2 = 1 + 3/2 sqrt(5) i, b^2 = 1 - 3/2 sqrt(5) i
    2) a) Undefined at one limit of integration
    b) Does not have a finite value
    3) a) 2-11i
    b) i) q=20 (z^3-11z+20=0)
    ii) z^2- 4z + 5
    iii) z = -4
    4) a) x = {-5 + 120n, 35 + 120n}
    b) 235
    5) a) c=4, d=-1
    b) i) -16I
    ii) enlargement scale factor 2, rotation 45 degrees clockwise
    iii) Fromleft to right, top to bottom: [[65536sqrt(2), 65536sqrt(2)], [-65536sqrt(2), 65536sqrt(2)]]
    6) a) Hyperbola crossing (3,0) and (-3,0)
    b) y = 4/3 x + 4, y = -4/3 x -4
    7) a) 39.60
    b) n(n+1)(2n+3)
    c) i) 2/3 r
    ii) k = 39
    8) a) y = 1
    b) (1, -1/2) and (-3, 3/2)

    Not sure if they're right, feel free to make corrections.

    that one matrix, it was really easy but i think i might have got the image and point the wrong way around and lost those marks
    You haven't got it the wrong way around, yours is right.

    Yep. What mark do you think you have got?
    I'm too afraid to count
    Well I went full retard on Newton Raphson, I don't know how many marks that was
    Made algebra error with sum to 60 thing, got k=39 but then the cubic didn't match the beginning of the question, so I don't know how many marks I'd get. Hoping for ecf
    Went full retard for asymptote, got the original asymptote but forgot the bracket for +3. One mark off I think
    The B^17 l totally got it wrong 2 marks off

    I may have lost method marks for few questions, I hope they are lenient

    what did people get for the newton rhapson one?
    i got like 39.59
    also when you had to prove that summation, was it n(n+1)(2n+2) or 2n+3?

    2n+3, I also got 39.59

    Anyone got their average of grade boundaries, and 100 UMS raw mark? I'm hoping around 68-69 will be enough for 100 UMS

    The 60 sum one was 4 marks.
    Also could you remember what you got for Q? For the complex question. P=-11 and Q=20?

    i think i got the summation one wrong

    what do you think the grade boundaries for an A will be? higher than 55?

    I had all the same answers as you apart from B^17 and 7a, I'm pretty sure it had to be an integer?

    should be (x-3) in brackets as the hyperbola was translated 3 to the right
    It was 3 to the left as k<0

    55 seems reasonable.

    the second bracket in the summation was definitely 2n+3, right?

    7a was a Newton raphson question so it doesn't need to be an integer.

    There were two parts. The sign change and the newton bit.
