Integration by Parts To reverse the chain rule we have the method of u-substitution. To reverse the product rule we also have a method, called Integration by Parts. The formula is given by: Theorem (Integration by Parts Formula) ˆ f(x)g(x)dx = F(x)g(x) − ˆ F(x)g′(x)dx where F(x) is an anti-derivative of f(x).

The formula for integration by parts is: ∫ = − ∫. To correctly integrate, select the correct function . The method to select this function follows a sequence, which means if the integral contains a certain expression, from this list, in order, select that expression as . Everything else in the integral is .
Integration by parts. mc-TY-parts-2009-1. A special rule, integration by parts, is available for integrating products of two functions. This unit derives and illustrates this rule with a number of examples.
