TECHNIQUES OF INTEGRATION
In this chapter we develop techniques for using these basic integration formulas to obtain indefinite integrals of more complicated functions.

2
Find Find INTEGRATION BY PARTS formula for integration by parts.
Example Example Find Find

3
Find INTEGRATION BY PARTS formula for integration by parts.
REMARK1: aim in using integration by parts is to obtain a simpler integral than the one we started with. REMARK2: How to choose u and dv to obtain simpler integral Example Find

4
INTEGRATION BY PARTS Example REMARK2: in some integral, we may need to apply integration by parts many times. Find

5
INTEGRATION BY PARTS Example REMARK2: in some integral, we may need to apply integration by parts many times. Find Example Find Example Find

6
INTEGRATION BY PARTS formula for integration by parts. Example Find REMARK3: sometimes a repeated application of integration by parts leads back to an integral similar to our original one. If so, this expression can be combined with original integral.
