Integrating Exponential Functions TS: Making decisions after reflection and review
Objective To evaluate the integrals of exponential and rational functions.

Exponential Functions
Test: Take the derivative of the choice of u. If you cannot find it elsewhere in the integrand, then use a different expression for u. Testing Zone: This expression is off only by a constant multiple.

Conclusion Integration by substitution is a technique for finding the antiderivative of a composite function. Experiment with different choices for u when using integration by substitution. A good choice is one whose derivative is expressed elsewhere in the integrand.
