Integrals of powers of sine and cosine (Trigonometric integrals)

In this lesson we apply the substitution rule for evaluating integrals of the form ∫ (sin x)^m (cos x)^n dx, where m and n are positive integer powers of sine and cosine respectively. We first look at the case where either one or both of the powers are odd numbers.

This video is part of a lesson series in Integral #Calculus for my Grade 12 students in the Philippine Science High School Main Campus.
