Product and quotient rules
You can figure out the derivative of f(x). You're also good for g(x). But what about f(x) times g(x)? This is what the product rule is all about.
This tutorial is all about the product rule. It also covers the quotient rule (which really is just a special case of the product rule).
See if you remember the five derivatives from the previous video.
If you know the product, quotient, and chain rules, try this exercise full of challenging derivatives.
