TECHNIQUES OF INTEGRATION In this chapter we develop

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

INTEGRATION BY PARTS formula for integration by parts. Example Find

INTEGRATION BY PARTS formula for integration by parts. REMARK 1: aim in using integration by parts is to obtain a simpler integral than the one we started with. REMARK 2: How to choose u and dv to obtain simpler integral Example Find

INTEGRATION BY PARTS Example Find REMARK 2: in some integral, we may need to apply integration by parts many times.

INTEGRATION BY PARTS Example Find REMARK 2: in some integral, we may need to apply integration by parts many times. Example Find

INTEGRATION BY PARTS formula for integration by parts. Example Find REMARK 3: 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.
