when m or n is odd.

        The technique is to break off the trig function that is to an odd power (if both are, break off the one that is to the

        lower degree), and write all the others using the identity sin  x + cos  x = 1.

















        Pretty simple, eh? However, when m and n are to an even power, the integrals are usually much longer.

        Example 6—


                           and n = 0 with both exponents even.

        In doing these problems, we will use the half-angle formulas:
