2. Computer simulation of the Indonesian tsunami of December 26, 2004 (8 minutes after the earthquake), created using models of wave motion based on advanced calculus by Steven Ward, University of California at Santa Cruz. 8 TECHNIQUES OF INTEGRATION In Section 5.6 we introduced substitution, one of the most important techniques of integration. In this section, we develop a second fundamental technique, Integration by Parts, as well as several techniques for treating particular classes of functions such as trigonometric and rational functions. However, there is no surefire method, and in fact, many important antiderivatives cannot be expressed in elementary terms. Therefore, we discuss numerical integration in the last section. Every definite integral can be approximated numerically to any desired degree of accuracy.Section 5.6rational functions

3. The Integration by Parts formula is derived from the Product Rule: Integration by Parts Formula

4. The Integration by Parts formula is derived from the Product Rule: Integration by Parts Formula Because the Integration by Parts formula applies to a product u(x)υ (x), we should consider using it when the integrand is a product of two functions.

7. Integrating by Parts More Than Once

8. Integration by Parts applies to definite integrals:
