1< Use a change of variables to evaluate the following definte integran.

Sure thing! A common change of variables technique involves substituting a new variable to simplify the integral. For instance, if you have the integral of a function involving ‘ax + b’, you might let \( u = ax + b \). Then, you can express ‘x’ in terms of ‘u’, which often simplifies the integration process. Additionally, be careful with the limits of integration! When you substitute your variables, be sure to also convert the limits of integration from x-values to u-values, ensuring the bounds match the new variable’s context for a proper evaluation. Happy integrating!
