Trigonometric Integrals Even Powers. Some of the following trigonometry identities may be needed. This calculus video tutorial explains how to find the integral of trigonometric functions containing odd and even powers using trig identities and.

Lecture 8 Integrals Of Trigonometric Functions from img.yumpu.com

Integration, improper integrals, trigonometric integrals, integration by partial fractions. Section 2.2 powers of trigonometric functions. Will not produce an integral that involves an even number of the other type of trigonometric function.

We start with powers of sine and cosine.

Since the powers are relatively nice, you could rewrite everything in terms of cosine or sine, and use one of the. First let us work through an example. To integrate an odd power of sine or cosine, we separate a single factor and convert the remaining even power. Notice that the integrand contains an odd power of cos.

Even if we convert somehow sines to cosines (or vice versa), integral is still very difficult to take advantage of trigonometric identities, double angle formulas and formulas that convert product of trigs into sum.
