    Here dude
    Edit: your told points in z plane is from real axis hence y is 0 and so equate with w plane imaginary equals 0

    Points on the real axis on the z plane means that Im z = 0

    Because it's a straightforward module taken by able candidates.

    Repetitive questions..it's not that it's an easy module really. But look at fp3 last year in comparison. Like 59 for an a* if I recall correctly. Simply because fp3 asked a couple of weird questions. fp2 requires quite a lot of competence but everyone who sits it has that competence and most will tend to steamroll any paper with standard questions regardless of how awkward the algebra is or whatever.

    Can anyone link me to the June 2013 withdrawn paper, I cannot seem to find it and the one on physics and maths tutor isn't printable as when you go to print the pages are blacked out

    My core is reasonably strong but when it comes to choosing the integration limits for polar coordinates I just seem to consistently get it wrong, I think I've got some sort of misconception or something, can anyone help lol?

    Put up an example and explain your reasoning.

    2root3, used 2 of the points I already knew with the C2 distance formula on (7,4) and (4, 4+root3) then did (x-x1) squared + (y-y1 squared) with those two coords
    Also just a general rule, if you pick two points on a circle and find their perpendicular bisector. Does that always go thru the centre?
    Thanks this has been bugging me for ages now.

    Yeah, Draw the isosceles triangle to the centre (the two lines which are both radii) Then it's a result that the bisector of the angle at the centre coincides with the perpendicular bisector of the base so it indeed goes through
    I think..bit tired. Got a geometry exam tomorrow though lol

    What years papers do you guys think have been the hardest? Did all the past papers ages ago so can't really remember them. Was going to choose the trickiest few and do them before the exam. Thanks

    Went crap because I'm retarded, freaking average year 12 would have done better on that piss easy exam but I apparently have a thinking deficiency...
    But thanks for the good words anyway

    Heres a quick question you might want to try for extra practice...

    Use the method of differences to show that

    \mathrm{cosec}\hspace{3pt}2 + \mathrm{cosec}\hspace{3pt}4 + \mathrm{cosec}\hspace{3pt}8 + \ldots + \mathrm{cosec}\hspace{3pt}2^n = \cot 1 - \cot 2^n

    (Hint: Think about trig identities linking cosec and cot)
