Description: Learn how to use the Power Rule to find Integrals or Antiderivatives. Just like there is a Power Rule for finding Derivatives, there is also a simple, straight-forward Power Rule for finding Integrals. Since Derivatives and Integrals are opposites of each other, you just have to do the opposite steps of the Derivative Power Rule in the opposite order to find the Integral of any variable raised to a constant power.
