1. 2.4 The Chain Rule
Use the Chain Rule to find derivative of a composite function.
Use the General Power Rule to find derivative of a function.
Simplify the derivative of a function using algebra.
Find the derivative of a trigonometric function using Chain Rule.

2. Theorem The Chain Rule
If y = f(u) is a differentiable function of u and
u = g(x) is a differentiable function of x, then
y = f(g(x)) is a differentiable function of x and
or, equivalently,

3. Theorem 2.11 The General Power Rule
If y = [u(x)]n, where u is a differentiable function of x, and n is a rational number, then
or, equivalently,
