Integrating Composite Trigonometric Functions by Substitution (9.3.1)

Question 1

• Integration by substitution is a technique for finding the antiderivative of a composite function. A composite function is a function that results from first applying one function, then another.

Question 2

• If the du-expression is only off by a constant multiple, you can still use integration by substitution by moving that constant out of the integral.
