Worked problem in calculus. The indefinite integrals of the form int cos^m(x) sin^n(x) dx break into two cases: one of m or n odd, or both m, n even. The first case allows for a straightforward u-substitution. The other requires the half-angle identities for cosine and sine. Examples are (a) sin^5(x), (b) sin^3(x) cos^3(x), and (c) sin^2(x) cos^2(x).
In this series, Dr. Bob covers topics from Calculus II on the subject of advanced integration techniques, such as Integration by Parts, Trig Integrals, Trig Substitution, Partial Fraction Integrals, L'Hopital's Rule, Improper Integrals.
