    Mr M for part 4ii, I changed infinity to r, as equated normally, and got the answer that a=2+r just the positive answer, any marks for that? And on that tangent question I worked out the equation right, but forgot to change the integral limits, how many marks lost would that be ? Also I love your mark schemes!

    Also will 65-67 ish marks be above 90 ums for this paper as I felt it was a reasonably easy/ very fair paper

    On 8ii I got as far as this:
     

\ x(\log_2\frac{a}{b}) =2


    How many marks do you think I would get out of 5?
    Thanks.

    Hi Mr M. Thanks for the answers a usual,
    1. For 6ii) i showed how the inequality was formed, however did not read the question and did not find N, how many marks lost.
    2. For 7ii) I differentiated the curve, found the tangent equation and that it crosses the x axis as 5/3, however after this i integrated between 5/3 and 1 which i have now realized was wrong, how many marks lost?

    Thanks, Z

    I don't actually know, but at a guess, I'd say 2-3.
    MrM will be able to give you a definite answer.

    Mr M, what did you think of this paper in terms of the difficulty of it, compared with recent C2 papers? Thanks

    For question 8iii:

    I did (where log =log2)

    a^x=4b^x
    a^2x=4(b^x)(a^x)
    2xloga=log4 + xlogb +xloga
    2xloga=2 + x(logab)
    2xloga = 2 + x (log2=1)
    2xloga -x =2
    x(2loga -1) =2

    therefore x=2/ (2loga -1)


    how many marks would i get (if any)?


    thanks

    How does Mr M get these answers?
    The mark schemes obviously aren't released yet and if he is a student, surely no-one can remember their answers fro an entire exam paper!

    Is Mr M a teacher?

    Definitely on the lower end of average difficulty, this paper if not one of the easiest. So the grade boundaries will be higher compared to previous versions. I think it's Easier than june '12 and jan '12 and much easier than jan '13. So based on past boundaries, I'm pretty sure it's about 60 give or take one or two, for an A.

    For the area under the curve how many would I drop for, writing down it was the integral- the area of the triangle. I messed up calculating the x coordinate so in the end just guessed it as 2, in a last ditch effort :P

    also for question 8 didn't b have to be a negative number?
    Get 1 mark for writing that down and no.
