    These are my answers to todays FP2 exam. Not all of them are necassarily correct, please feel free to correct me on any you think are wrong. Not sure about the question numbers.
    FP2 June 2016
    1.
    a) A=4
    b)  \frac{50}{609}
    2.
    a) i) \beta=1-2i
    ii) \alpha\beta = 5
    b) \gamma = \frac{1}{3}
    c) p=-5 q=-7
    3. a) Show that s is the required integral
    b) \ln7-3/4
    4. a) \frac{\sqrt3}{2(1+3x)\sqrt(x)}
    b) \frac{\sqrt3\pi}{18}
    5. Induction Q.
    Trivial in the case  n=1 since clearly  1+p \geq 1+p
    Assume true for  n=k
     (1+p)^(k+1) = (1+p)^k(1+p) = (1+kp)(1+p)

= 1 + kp + p + kp^2 \geq 1 + (k+1)p as  kp^2 \geq 0
    Thus true for  n=k+1 so true for all positive integers n by induction.

    6.a) Show that Q
    b) 6\sqrt3 + 3arccosh2 + 5
    7. a) 8
    b)i) Sketch with a circle with centre  -4\sqrt3 + 4i radius  4
    ii) 2\pi/3
    c) Roots are  2e^\frac{ix\pi}{18} where x=-7,5,17
    8. a) Show that Q
    b) Roots were  i\tan(x\pi) where  x= 1,3,5,7
    c) i)  1
    ii)  6

    Oh, well at least you're lucky that you probs got an S in STEP I, got S's in most I mocks and then not in the real thing . STEP II ok-ish, STEP III ok. Idk about grades, don't want to try to predict too much now.

    On the method of differences question I got the correct answer but forgot to complete the working. Basically I showed what it would be for 1, 2 and 3 then I cancelled those and continued down for n-2, n-1 and n, but forgot to go back at the end and write what those terms would be. So even though I got 50/609 would I not get full marks?

    Damn it, this was a flop for me, minimum 47 marks i think, this can be atleast 70 UMS right? Was harder than majority of past papers..
