TECHNIQUES OF INTEGRATION Due to the Fundamental Theorem of Calculus (FTC), we can integrate a function if we know an antiderivative, that is, an indefinite integral. We summarize the most important integrals we have learned so far, as follows.

TECHNIQUES OF INTEGRATION In this chapter, we develop techniques for using the basic integration formulas. This helps obtain indefinite integrals of more complicated functions.

TECHNIQUES OF INTEGRATION We learned the most important method of integration, the Substitution Rule, in Section 5.5 The other general technique, integration by parts, is presented in Section 7.1

TECHNIQUES OF INTEGRATION Then, we learn methods that are special to particular classes of functions—such as trigonometric functions and rational functions.

TECHNIQUES OF INTEGRATION Integration is not as straightforward as differentiation. There are no rules that absolutely guarantee obtaining an indefinite integral of a function. Therefore, we discuss a strategy for integration in Section 7.5

The rule that corresponds to the Product Rule for differentiation is called the rule for integration by parts . INTEGRATION BY PARTS
