This technique, which is analogous to the chain rule of differentiation, is useful whenever a function composition can be found within the integrated. (2 y+9)}$$. comes in. Click HERE to see a detailed solution to problem 14. For example, since the derivative of ex is , it follows easily that . U-substitution in definite integrals is just like substitution in indefinite integrals except that, since the variable is changed, the limits of integration must be changed as well. Click HERE to see a detailed solution to problem 8. U-substitution is an integration technique that specifically reverses the chain rule for differentiation. ??
