$$\int_{0}^{2pi} -(cos^2 x)(sinx) dx$$

There is a standard technique for integrals involving an odd power of sine or cosine. That is what Matt is talking about. Check your textbook for that.

it wasn't what i was knowingly talking about, i was just pointing out in fact that integrating that is not a 'trig' problem, and belongs to a far more generic type of integral.
