      3.If m = 2k,n = 2l are both even, write sin2x = 1 2 (1 cos2x) and cos2x = 1 2 (1+cos2x) to obtain Z sinmxcosnxdx = 1 2k+l Z (1 cos2x)k(1 +cos2x)l dx which yields integrals of powers of cos2x. If these powers are odd, then we use the strategies above, if they are even we can repeat to find integrals in terms of cos4x, etc.

One can see immediately, that f (y) ≤ 1 hence the maximum is 1 and that happens when y = 0, x = ±1. 2. Find the Maclaurin series for the function: f (x) = Rx2 0 e− ...
