    For question 10(ii) of the January 2014 FP1 IAL paper would this get the marks for the induction bit of the question? It doesn't show my method in the mark scheme but it seems to work.Thanks!

    It's still correct of course, but you could have used 5 instead of 21.

    6b is not on the UK spec either; Its always 10 marks of non UK spec stuff in the IAL papers.

    Only in multiples of 45 degrees, whereas on IAL it can be rotation of any angle.

    I think it's just the F1 papers were that comes up and not FP1 - not sure to be honest. I can't see a difference between IAL/R FP1 and UK FP1 papers.

    you can work it out with logical thinking and theta value comparisons - i made mistakes for taking rt 9 as solely +3 (-2 marks) and lost another mark for the coordinate qn (-2 marks)

    Yep, so your original mark should suffice.

    Does anyone know how we would do inductions with inequalities like in this question? Not seen one like this before! Thanks Attachment 531129
    Where's this question from?

    When given the roots to a quadratic equation - e.g. 5 + 3i, 5 - 3i

    Is it ever the case when the 'x-squared' term has a coefficient in front of it? in that case what would you do?

    Doesn't matter, a quadratic equation with roots 5+3i and 5-3i is
     x^2 -10x +34 Then you could just multiply through by any real number and it will have the same roots, so  2x^2 - 10x +68 or  \frac{1}{2}x^2 - 5x +17 both have roots  5\pm 3i for example.

    When I was writing 'any real number,' I was thinking about how someone could correct that and I didn't even think of 0.
