The product rule is used to differentiate products of two functions that cannot be expanded easily.
It is an important rule that is used extensively in calculus. In the tutorial I show you what it is and how to use it.

Product Rule:

  • \text{If }y = uv \\ \\ \text{then } \dfrac{dy}{dx} = u \dfrac{dv}{dx} + v \dfrac{du}{dx}
