A particular solution of the differential equation
3 y^2 dy/dx=4 ( y^3 + 1 )cos^2(x)
is such that y = 2 when x = 0. The diagram shows a sketch of the graph of this solution for 0 ≤ x ≤ 20;
the graph has stationary points at A and B. Find the y-coordinates of A and B, giving each coordinate
correct to 1 decimal place.

then find me some good ones and help me with this stuf....
how desperate am i that i find help for maths in some sucky notes _-_
on a serious note though... i did integration and differentiation recently from these starting from the very basics (P1) and working towards almost the end and felt like it did help me....

If P(x) =x^3 - 12x +16
then what is P(x^2) ? any help
then what is P(x^2) ? any help

it's quite simple
if it was given P(2), you would have substituted 2 in the equation
same way, now put x^2 in place of x in the equation
that gives you
P(x^2) = (x^2)^3 - 12(x^2) + 16
= x^6 -12x^2 + 16

I don't have a copy of o/n 2013 papers yet. Can you attach the paper and repost??

things I didn't mention in the picture
cos2x = 2(cosx)^2 - 1
1+cos2x = 2(cosx)^2
I directly substituted this in the sum while finding both modulus and argument
and the last line about getting theta for argument
it's easy to understand how tan inverse of tanx = x
(I used x for angle)

This is the link for oct/nov papers!
i actually also had a doubt in this : http://maxpapers.com/category/quali...l/cambridge/a-level/a-level-mathematics-9709/

from the last line you can prove the real part of 1/z is constant i.e. 1/2
