Method, practice, and harder questions
The Chain Rule
If \(y = f(u)\) and \(u = g(x)\), a function nested inside another, then \(\dfrac{dy}{dx} = \dfrac{dy}{du}\times\dfrac{du}{dx}\). Below: the method, ten foundational questions, then five harder ones.
Next up: the quotient ruleWhy dividing two functions is really the product rule wearing a disguise.
