10-108.

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. Homework Help ✎

You should recognize the integrand as a form of the derivative of tan^{–1}(*x*).

The denomintor needs to be of the form *a*^{2} + 1.

Use substitution. Let *u* = *x*^{2} + 4.

Factor the denominator then use partial fraction decomposition.
