You will be able to investigate, derive, and use the Chain Rule
I don't know about you, but I'm just about done applying the Chain Rule to polynomial, rational, and power-based functions. Let's try using the Chain Rule on a composition of trigonometric functions. We'll start by deriving the derivative of sec(x) again. Duration: 7:51
Second derivatives, an inception of trig functions, and more on Examples 12 through 14. Duration: 6:07
