sin2x and cos2x types

In this first video, you are shown how to integrate terms containing.

\displaystyle\int \sin^2 x \text{ } dx

and then asked to try:

  1. 3\displaystyle\int \sin^2 5\theta \text{ } d\theta

Now I take you through the

\displaystyle\int \cos^2 x \text{ } dx

and then asked to try:

  1. 5\displaystyle\int \cos^2 8\theta \text{ } d\theta
