NettetPeel off a sin x and place it next to the dx: Apply the trig identity sin 2 x = 1 – cos 2 x to express the rest of the sines in the function as cosines: Use the variable substitution u … NettetSince both exponents are odd, there are at least two ways to evaluate the integral. We choose to rewrite cos2xas 1 sin2xand then substitute u= sinx, du= cosxdx. This gives Z sin3xcos xdx = Z sin3x(1 sin2x)cosxdx = Z u3(1 u2)du = Z u3u5du = u4 4 u6 6 du = sin4x 4 sin6x 6 + Cdu Case 2. Both exponents are even.
