This video explains how to use power reducing formulas to reduce our problem so that the problem has the highest power of 1. The problem that we will be reducing is sin^2(x)cos^2(x). Pay close attention when foiling that (2x) is a variable and does not get foiled. Also, pay attention to when we substitute (m) for 2x and know that you will have to plug 2x back in for the value of m. Lastly, you may have to use the power reducing formulas more than once to reduce everything down to the highest power of 1.
