# The derivative of f(x)*g(x)/h(x)

RandomMystery
What is the derivative rule for a function times another function divided by another function?

Just treat f(x)*g(x) as one function, say v(x). So you have the derivative of $${{v(x)} \over {h(x)}}$$ which you differentiate like normal. When you differentiate v(x), you'll simply have a product rule to deal with.
