integrate: at the moment, I can only think of the cos^2x = 1/2cos2x + 1/2 thing, but I think that it will make the integration look really ugly any other ideas for how to integrate this nicely? Thanks in advance

Thanks in advance i would go with substitution: t = cos^3(x) then you need to integrate
