The power rule allows one to calculate the derivative of a power of a function in terms of the derivative of the function itself. The power rule states that
<math> \frac{d}{dx} (x^n) = nx^{n-1} </math>
for all integers <math> n </math>. This rule is useful when combined with the [[chain rule]]. As an example we can compute the derivative of <math> f(x) = (\sin(x))^n</math> as
<math> f'(x) = \frac{d}{dx} (\sin(x))^n = n(\sin(x))^{n-1}\cos(x) </math>
