    How many marks lost for getting 32(In2)^2 +32In2 - 12
    I'm confused; I believe that is the correct answer.

    If you got an answer wrong on part a and used it for part b, do you still get method marks on part b?

    Yes, they usually allow follow-through marks

    Yes; you get the method marks but not the accuracy marks. Provided, of course, your method is correct.

    These are all my solutions. sorry for the poor quality but should be still readable
    Shouldn't it be - 8y for the implicit differentiation question? You put +8y

    Think you need to use sin rule?
    I thought you would just need to use the normal trig ratios

    Hey, if in 3 I integrated from 0 to ln2 instead of 4ln2 how many marks will that be?
    Also if in 8 I used 2-1/ln3 as my upper limit instead of 2 how many marks will that be? Everything else was right.
