$\int^{\pi}_0(cosx^{2}-2a_{0}cosx-2a_{1}cosx+a_{0}^{2}+2a_{0}a_{1}x+a_{1}^{2}x^{2})d x$

Power reducing for cos?

I don't think so.

Every term can be integrated in a staightforward manner (assuming a: constant) with the exception of the first term. In wich case

Let $u=x^2$...

3. Yeah.... Scratch my last post. I misread the NFO. Sorry.

Yeah, you gotta get that square outta there.

Power reducing won't work because it is $\cos(x^2)$ not $(\cos{x})^2$

After seeing your LaTeX code, I'm wondering which one you meant to say: $\cos x^2$ or $\left(\cos x\right)^2$?
