    Why not? Fairly sure it is because we do graph sketching in C1/2.


    yh i know but even something like this?
    "sketch the graph of g(x)=cos3x +2xcos3x" (p4 jan 03 qn 7)
    (check the MS cuz you have to workout g(x) )

    Yeh so
    (2x+1)(cos3x)
    So an oscillating wave bounded by 2x+1 and -(2x+1) with zeros at 3x=(2n+1)pi/2

    I hope you know that this is not a sum. It is a polar equation.

    How else are we meant to do it?

    Edit: I just realised what you meant... I've been reading up on too much set theory and logic.

    Okay so the centre's (-4/5,0) and radius is 6/5. How do we do the b part?

    Well, you know what |z|=2 maps to, so what does |z| \leq 2 map to?

    okay z=2 maps to the circe, so z \leq 2 should map to the circumference of the circle and everything inside it?

    Try substituting the origin O (0, 0) to see where it maps to. It works as a nice test to see where the region lies. Zacken's method is probably more formal but I thought I'd show you a quick alternative as well

    I think most people do it in their A2 year once they've learned C3/C4.

    When finding the area of R2 why do we integrate equation 2?

    What is wrong with integrating equation 1 with limits pie/2 and pie/6

    thanks

    They seem to increase by one raw every year. :afraid:

    The papers I've done so far have been trivial though, 2010-13. Which ones have you done?
    Hey mate, sorry for the late reply. Not many tbh, find that most of the questions are v similar so not much practice needed. Hardest part for me are transformation questions!
