    You're answers to 1,2,3,5,6,7,8,9B) seem familiar but not 9 or 4 :/
    Think I got a=-28 for 4)b and d=34
    I though 9)a) was 3^(n/12m) (possibly with m and n the other way round)
    I distinctly remember trying to work out A and D and they came out to a=28 and d=-2
    And i definitely got 3^(m/2+6n)

    How did people do q6bii (the 2nd transformation question)? The one with root(x^2+9).. could someone explain it to me?

    I think it was -6n, because it's a division, right??
    thats right

    the question gave us a factorised quadratic so in first (1-tanx) it was one solution and the other one you had to sub in tanx=-5/4 from previous question and equal it to zero therefore 2 solutions from each so 4 in total
    Smh so dumb... How many marks would I have lost for only getting -5/4?

    Lol I don't know whether it should be 6n or -6n

    Dam I think I divided the powers :/// stupid me. How many marks was that?
    4 marks I guess

    Don't mean to worry you, but that wasn't the last question D:


    but yeah, if you solved to 5+3costheta, then you'll get at least half the marks

    I think it should be m/2 -6n as when you divide you take away powers?
    Ye I edited my post, I agree

    well depending how many marks were the solutions worth which could be 1 for 2 solutions or 2 for 2 solutions so i think you will loose 1 mark for sure but it can be 2 as well if the solutions were worth 1 mark each

    I think I lost about 6 marks if I got everything else right so 69/75, how many UMS (approximately) would that be?

    Updated - Unofficial Mark Scheme.

    Made a few errors so here it is:


    1. b) a=-2
    2. b) x=-0.861
    c) reflection in y-axis
    3. a) 3x^-1/2 - 1
    b) y=6
    c) y + 2x = 13
    d) k = 5.5
    4. b) d = -2, a = 28
    c) Sum to 21 - sum to 3. Can't remember exact.
    5. b) area = 19.9
    c) perimeter = 13.8 (something like that)
    6. a) 65.6
    b) i) translation (0,5)
    ii) stretch in X-direction 1/3 sf
    7. b) -1648
    8. b) can't remember! Tan(X) = 1 and tan(X) =-5/4
    c) lowest = 2, when theta = pi
    9. a) c^(m/2 -6n)
    b) X = 5/2

    should be -6n because powers were dividing

    Whole question was 3 marks so I probably lost 2, what did you get for the solutions? Did you get 2 or 4 solutions?

    I'm pretty sure a was 28 and d was -2

    I got 4. i think they were 45,(180-45), and some decimals from the other pair.
