$\displaystyle \int^{\pi}_0(cosx^{2}-2a_{0}cosx-2a_{1}cosx+a_{0}^{2}+2a_{0}a_{1}x+a_{1}^{2}x^{2})d x$ Power reducing for cos?

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 $\displaystyle \cos(x^2)$ not $\displaystyle (\cos{x})^2$
