Again, make a substitution $\displaystyle u=sin\theta \rightarrow du=cos\theta d\theta$. Substitute into the integral and you will now have:

$\displaystyle \int u^6 \,du$.

Integrate from here and substitute u back in and then you'll have your answer! Hope this helped you out! :D - May 11th 2008, 07:53 PMMathstud28
