    This video explains how to integrate power of sin and cos multiplied together, such as (cos x)^3. These techniques use u-substitution and using the fact that (sin x)^2 + (cos x)^2 = 1. In some problems, it is necessary to use double angle formulas to simplify and integrate. Some good examples are done in this video and many different techniques are explained. Finally, the entire lesson is summed up at the end of the video.

    I found this video extremely helpful. My math teacher did not explain integrating sine and cosine to powers very well at all! This video taught me everything I needed to know in a clear, concise manner with detailed examples at a slow enough pace that I was still able to follow and understand.
