Substitution for Definite Integrals. Substitution can be used with definite integrals, too. However, using substitution to evaluate a definite integral requires a change to the limits of integration. If we change variables in the integrand, the limits of integration change as well.
Section 5.8 : Substitution Rule for Definite Integrals. We now need to go back and revisit the substitution rule as it applies to definite integrals. At some level there really isn’t a lot to do in this section. Recall that the first step in doing a definite integral is to compute the indefinite integral and that hasn’t changed.
On this worksheet you will use substitution, as well as the other integration rules, to evaluate the the given de nite and inde nite integrals. Steps for integration by Substitution 1.Determine u: think parentheses and denominators 2.Find du dx 3.Rearrange du dx until you can make a substitution 4.Make the substitution to obtain an integral in u
"Integration by Substitution" (also called "u-Substitution" or "The Reverse Chain Rule") is a method to find an integral, but only when it can be set up in a special way. The first and most vital step is to be able to write our integral in this form: Note that we have g(x) and its derivative g'(x) Like in this example:

Substitution and Definite Integrals The fourth step outlined in the guidelines for integration by substitution on page 389 suggests that you convert back to the variable x. To evaluate definite integrals, however, it is often more convenient to determine the limits of integration for the variable u.
Substitution may be only one of the techniques needed to evaluate a definite integral. All of the properties and rules of integration apply independently, and trigonometric functions may need to be rewritten using a trigonometric identity before we can apply substitution.
