The key to solving any integral of this form is to use the cosine rule:
cos(2x) = cos2(x) - sin2(x) = 2cos2Answered by Daniel F. • Maths tutor36075 Views

If you aren't lucky enough to be told in the question, the first thing we have to do is know when we should you integration by parts.
As you will be aware, it is not easy to directly integrate terms involving sin^2(x) and cos^2(x), so we use a substitution to turn them into something which we can integrate.
From the double a...
The integration by parts formula takes the form:
int(uv') = uv - int(vu')
where v' = dv/dx and u' = du/dx
A lot of the art of using the integration by part...
