16 96 usubstitution For more complicated integration problems, simple rules for integration might fail, and ou ma have to make some tpe of substitution to be able to integrate. In this course, a common substitution will be to let u = the radicand radicand part of the epression and to change the variable throughout the integral before integrating. You should use this method of substitution (called usubstitution) onl when simpler methods don t work. It should be our last resort. Procedure for usubstitution: (for d problems requiring the method). Let u radicand (part inside the smbol).. Solve for (in terms of u).. Differentiate the equation from Step. 4. Find d. 5.
