I know how to prove the quotient rule by using the definition of a derivative using limits (Newton's style). I just saw a proof of the product rule using Leibniz's concept of differentials on Wikipedia. https://en.wikipedia.org/wiki/Product_rule#Discovery
Does anyone know of a Leibniz-style proof of the quotient rule? I was not able to find it and when I tried doing it myself I got an extra term in the denominator.
