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 f x g x dx F x g x F x g x dx where F x is an anti derivative of f x TECHNIQUES OF INTEGRATION WORKED EXAMPLES Find the following integrals 1 Z 3x2 2x 4 dx See worked example Page2 2 Z 1 x 2 1 x 1 dx See worked example Page4 3 Z x x 1 2 dx See worked example Page5 4 Z x 1 p x dx See worked example Page6 5 Z 2x dx See worked example Page7 6 Z 1 3x 1 dx See worked example Page8 7 Z 3sec2
For example if an object is thrown straight upward at 19 6 m sec its velocity function is v t 9 8t 19 6 using g 9 8 m sec2 for the force of gravity This is a straight line which is positive for t 2 and negative for t 2 The net distance traveled in the first 4 seconds is thus Z 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
