If $f(x) = \frac{u(x)}{v(x)}$, what is the derivative rule for the quotient of two functions (where $v(x)
eq 0$)?

Question

If $f(x) = \frac{u(x)}{v(x)}$, what is the derivative rule for the quotient of two functions (where $v(x) 
eq 0$)?

Accepted Answer

According to the quotient rule, $\frac{d}{dx}\left\frac{u}{v}\right = \frac{u'v - uv'}{v^2}$.
