    It may ask you to express a complex number in mod-arg form, or vice versa (going the other way, simply expand the brackets on it - really easy). You don't do anything more with that til FP2.

    Have you done (I think) C4 yet? That covers implicit differentiation and provides a much more elegant way of finding the eqn to the tangent in the parabola questions. Otherwise, here's how you do it:

     y^2 = 4ax 



y = 2\sqrt{a} x^{\frac{1}{ 2}}



{\dfrac{dy}{dx}}  = {\sqrt{a} x^{\frac{-1}{2}}}

    Then put in your x coordinate to get the gradient of the tangent at that point.
    Then use the equation  y-y_1 = m(x-x_1) Stick in the gradient as  m then x and y coordinates as  x_1 and  y_1 and off you go!


    I don't think you need any knowledge of proofs except for induction in FP1.
    Thank you thank you thank you!!
    I dont feel too bad about this exam actually......
    No i havent done C4 yet....just finished C3 (exam on monday was hell)

    Yeah definitely. C4 last year was 69 for an A. 69 will probably get 90ish this year.

    I think all boards are making things tougher this year. For AQA C3, C4, M2 and FP2 have been the toughest papers ever. And the C4 last June was 65/75 for 100 UMS! Scary times, but I do like a challenge.

    Same I hope, I feel like I must have neared 100% at least but you can never be too sure

    Did a bit of STEP II this morning, didn't go great but I misread a quite easy question which made me go wrong massively, and I wasn't putting much effort in honestly.

    Need to ease into it until I'm ready to plough through questions

    I'd agree with this, though I thought C4 was quite ordinary/easy. FP2 on AQA was an absolute killer

    Personally I could handle everything, except for the evil 6 marker at the end (damn you vectors!). M2 is meant to be extremely standard every year. That was not the case this year. Just hoping grade boundaries are nice to get me into the 90s. Aha yeah, my teachers were screwing when they saw FP2. Told us to watch out come June. :p:

    Yeah I've been able to scrape an A in some of the hard papers! Cross fingers that they're nice don't like doing the mathematical induction question, so hope that ones alright! Good luck to you on monday!
