Quotient rule

In calculus, the quotient rule is a method of finding the derivative of a function that is the ratio of two differentiable functions. Let ${\displaystyle f(x)=g(x)/h(x),}$ where both ${\displaystyle g}$ and ${\displaystyle h}$ are differentiable and ${\displaystyle h(x)\not =0.}$ The quotient rule states that the derivative of ${\displaystyle f(x)}$ is
