Problem 13. You don't have to use the Weierstrass substitution for trigonometric integrals. Sometimes you can find a substitution that works more easily (fewer steps) than the Weierstrass. By "trigonometric integral", I mean the integral of a rational function of sine and cosine. You can use the Weierstrass substitution with integrals like SVsin(@) de, but you won't get an integrand having an "elementary" antiderivative. However, the Weierstrass substitution always yields an integral we can evaluate explicitly, whereas an ad-hoc flavor-of-the-day...
