Deriving the product and quotient rules using the chain rule. I prove the formulas for the product and quotient of derivatives from calculus by applying the chain rule to a clever function of several variables. This is like a unified theory of everything, but for the chain rule and shows how powerful it is. I'm hoping this is useful for any undergraduate taking calculus and analysis and it gives a useful way of remembering it for math exams.
