Course: Calculus II
Topic: Integration Techniques
Subtopic: Trigonometric Integrals


Our focus today is on evaluating integrals of products or quotients of trigonometric functions such as ∫sin3x cos2x dx and ∫sec5x dx, or ∫sin5x/cos3x dx. These trigonometric integrals may require rewriting via identities, u-substitutions, and/or integration by parts. Each type of integral requires a particular plan of attack which we study in this lesson.


By the end of this topic you should know and be prepared to be tested on:


Define: products of trig functions, quotients of trig functions, trig function of a sum or difference
