    For 9iii I misread the q and used my value for a from the previous question but got the right solutions just with my a subbed in. How many do you think that would lose?
    You might get 2 for using tan and solving your equation.

    Hi Mr M, thank you for all these answers, it really helps a lot.

    Which question is it that the answer is k=1/9 for? I can't find it in the answers you provided but I keep seeing people saying that they got that as an answer.

    Thank you!!!

    Also on the final part of the sequences question where we had to work out N;

    I got up to N/2(10 + (N-1)1.5) - 1200 > 0
    Got 1.5N^2 - 8.5N + 1200 = 0

    It isn't a correct answer. There is a scale factor of 1/9 in 8ii.

    Drop 1. It said you had to give the exact area. In fact, you'll drop all the marks if you just typed that integral into your calculator and didn't show any working.
