Integrating Composite Exponential and Rational Functions by Substitution (9.3.2)

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

• You may need to experiment with several choices for u when using integration by substitution. A good choice is one whose derivative is expressed elsewhere in the integrand.
