    how do you tell the difference between

    y= Acosnx + Bsinnx for the complementary function from dy^2/dx^2 +n^2y

    and y= Ae^-nx +Be^nx.

    If you have
    dy^2/dx^2 +n^2y , this will give k^2= +/- ni , so because it isn't real is it y=Acosx + Bsinx

    dy^2/dx^2 -n^2y this will give k^2= n^2, so because it is real, is it y= Ae^(nx) +Be^(-nx)


    Is this correct

    One of the most difficult along with FP2 I think.
    The whole paper is about vectors, matrices, planes and things, which is good if you can get on with them, but I find it hard!

    Name:  440px-Circle_slices.svg.png
Views: 155
Size:  16.9 KBYou know the radius of the circle (=4) and you know the angle AOB. The length of the arc is  r\theta . The straight line is AB which should be easy to work out the length.

    What sort of knowledge from C3 and C4 do you guys reckon we might need? I know in past papers they've used partial fractions and Rcos(x-a).

    Also, does anyone have a condensed version of the 2015 paper? I want to redo it as when we did it in school way back I got an E
    I don't want to have to print off all the lined pages though since ink is so expensive.
