Integral of pie/2 to zero

Cosx dx/3+cos^2(x) =0.25ln3

hmmmmm .... first change the bottom into 3 + 1 - sin^2x and then use the substitution of u = sin^2x and that would make the question your doing much simpler =)

Actually a substitution is is much easier. Once you have . Then it becomes a difference of two squares. Partial fraction that and integrate the reciprocal functions. You'll end up getting logs.
