ABSTRACT
Integration by parts is a very important technique that is used often in engineering and science. It is frequently used to change the integral of a product of functions into an ideally simpler integral. It is the foundation for the theory of differential equations and is used with Fourier series. The chapter looks at standard integrals followed by various techniques to change integrals into standard ones; integration by parts is a particularly important technique for integrating a product of two functions. It describes appreciate when integration by parts is require, integrate functions using integration by parts and evaluates definite integrals using integration by parts.
