    Well, I'm 80% sure the answer is 5. I differentiated the equation and got 5. double checked it as well.
    I got 3....There were 2 values but u could check both with the second derivative...
    For min it had to be a positive. The max point was next to the given point (1,something)

    Its 1 to 3, i checked with my graph drawing program because i remebered the cubic, it was y = x^3 - 7x^2 + 15x + 3 graph of the required area is below, its the unshaded finite region. I got Q(3,12) but the next section i thought x = 4 :/ so i used the wrong values.

    Oh no!! You're right.

    Because then it asked you to prove PQ a parallel line to x-axis. both y-coord are 12 so that means, it has to be parallel.




    Gosh, I should bloody stop looking at this thread!! lol

    the + or - sqaure root of 3 question.......i done it by substitution, do you think i will get it right??

    The exam was a bit TOOOOOO easy, do you not think the boundaries will shot up, u have to try and think of any points that ypu actually may have dropped!! dor the last trignometry question did any1 else get:

    cos y = 1/3 cos y = -3
    y=..... impossible

    ??

    I've just come out of 4 solid hours in that exam hall..

    P1 went ok.. except for one mother of a question (AQA).. this was question 7 part b.. where you had to find x for sinx^2+sinx-1=0..

    hmm.. I bet the answer is really easy- but looking at it now I still can't work it out

    i didnt do that exam bored... but substitue sin with X

    then you have a quadratic. Solve it using factorisation. and then make the answer equal to sin &
    (sin theta.. >!)

    i got cosy=3 cosy= -1/3
    i feel i've messed up on this one...
    How does the whole grading thing work... do they add marks for all 3 papers and average
    or do you need As in all 3 papers to get an A or what?

    yeah the factorisation part is the bit I couldnt do..

    I don't think you need to get A's in all the papers.. but I guess it depends if its high A's you got on the others.

    If you got 3 high A's at AS you only need to average an ABB at A2

    yes exam was very easy - i finished it in 35 minutes, then re-did it...the grade boundaries will be very high which is gay because i think i couldve handled a harder harder paper and still get close to 100% but hey oh well good that nothing to do with spheres or anything awkward came up.

    I couldn't factorise it! I got sin^2 x + sin x - 1 = 0.
    which i made u^2 + u - 1 = 0.
    Which I couldn't factorise, as hard as I tried.

    All of the other questions I had no problem with though.
