The product rule is the rule that enable us to compute the derivative of a product of two functions without simplifying the product first. It states that

$\frac{d}{dx}(fg)=\frac{df}{dx}g+f\frac{dg}{dx}$

Some people feel that memorizing the rule in the form

$(fg)'=f'g+fg'$ or $(uv)'=u'v+uv'$ are easier. The videos below will guide you to use this rule to find the derivatives of a product of two functions.
