Power Rule for Derivatives
Power Rule for Derivatives The power rule is one of a number of derivative rules in calculus. The power rule says that if a function is raised to a power, then the derivative is equal to that function raised to the same power times the original function's derivative. For example, suppose we are given a function f(x) and its derivative f'(x), then the power rule savs: If f(x) = xn, then f'(x) = nxn-1 The power rule is a shortcut…...
