    Could somebody explain how the method of differences worked given one of the terms wasn't a fraction?

    I wrote them out in like 4 different ways and couldn't get them to cancel out..

    Yeah everyone went on about that question after. I thought it was just C4?
    I meant I messed up so bad in that question that I didn't even have e2x sinx anywhere fun times

    Phew, thank you, I had pi/24 13pi/24, 25pi/24, 37pi/24, Is that Ok then?
    I assume so. You could probably work it out by looking at old past papers and mark schemes with the same thing.

    The second value for theta should be 13/24 not 13/14 typo?
    yeah that's still different to what I got so would still like to know how you did it? I'm awful at complex numbers.

    How were you supposed to do Q4? I did i.b.p. twice to get I = something + (1/4)I, but I don't think that's on the A-level syllabus.
    That was the intended method, yeah. And that's definitely on the A-Level syllabus. It's IBP and algebra.

    I got exactly the same as you. I labelled them as z1, z2 etc. respectively then just wrote z1 next to their appropriate location on the argand diagram and did a line from 0 to the approximate cross.
    Hope it's right, I lost at least 15-16 marks

    Take the r-3 out of the sum and evaluate it FP1-style, then do m.o.d. on the fractions.

    I = something + 4I

    but yh

    I mean, it's common sense. And all knowledge required to do this question is on the syllabus

    Same. I don't feel like it's looking good for FP3 either, I feel like I should start revising for it now.
    Well good luck. I've got M2 left so hopefully I can smash that

    Got 60-67, inclined towards 67.

    If so hopefully 67 is an A*

    I saw that it was going to be that and couldn't remember the formula for the sum of r. Ugh.

    In C3/C4? I don't think our class learnt it in any case.
