1. Examine the following integrals. Consider the multiple tools available for evaluating integrals and use the best strategy for each. After evaluating the integral, write a short description of your method. Homework Help ✎

$\sqrt{x^{2}}=\left | x \right |$

Simplify the integrand and then visualize the graph.
What type of symmetry does it have? What can you conclude about its area between x = −1 and x = 1?

This is an indefinite integral. Don't forget the +C.

Before you integrate, factor the numerator and simplify.

Integrating a derivative gives you the original function + C.
