## How To Know Which Trig Substitution To Use

### You can use trig sub. for a good deal of problems, but you can use #u#-substitution arguably even more. We use this technique when we have something like #intlnx/xdx# . If we are observant, we see that we have two functions - #lnx# and #1/x# .

- In mathematics, trigonometric substitution is the substitution of trigonometric functions for other expressions. One may use the trigonometric identities to simplify certain integrals containing radical expressions: Substitution 1. If the integrand contains a 2 ? x 2, let = ? and use the identity ? ? = ?. Substitution 2. If the

- In this section, we will look at evaluating trigonometric functions with trigonometric substitution. A lot of people normally substitute using trig identities, which you will have to memorize. However, Dennis will use a different and easier approach. He will use the idea of Pythagoras Theorem and make a relation with sine and cosine in terms of x to substitute. In more advance questions, we
