Calculus MTH 3100 Chapter 7 : Techniques of Integration 7.6 Integration by Parts Integration by parts is a rule that transforms the integral of products of functions into simpler, integrals. The rule arises from the product rule of differentiation. dx du v dx dv u uv dx d ) ( Integrating the above equation : du v dv u uv dx dx du v dx dx dv u dx uv dx d ) ( Rewrite the last equation, we obtain du v uv dv u Integration by Parts formula Example : Evaluate dx xe x 2 L36 138 L36
