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

$\int u^6 \,du$ .

Integrate from here and substitute u back in and then you'll have your answer! Hope this helped you out!

Alternatively $\int\cos(x)\sin^6(x)dx=\frac{1}{7}\int\bigg(\sin^7 (x)\bigg)'dx$
