Examine the integrals below. Consider the multiple tools available for integrating and use the best strategy. After evaluating each integral, write a short description of your method.
Use integration by parts.
You should recognize the integrand as the derivative of an inverse trigonometric function.
This is an improper integral, so a limit will need to be used to evaluate it.
The symmetry of the graph can also be used to evaluate the integral.
Review the first Fundamental Theorem of Calculus.
