Reverse power rule review
Review your knowledge of the reverse power rule for integrals and solve problems with it.
What is the reverse power rule?
The reverse power rule tells us how to integrate expressions of the form where :
Basically, you increase the power by one and then divide by the power .
Remember that this rule doesn't apply for .
Instead of memorizing the reverse power rule, it's useful to remember that it can be quickly derived from the power rule for derivatives.

Integrating polynomials
We can use the reverse power rule to integrate any polynomial. Consider, for example, the integration of the monomial :
Remember you can always check your integration by differentiating your result!
