precalculus.
8.2The definition of the derivative

9.2The derivative as a function
Here we study the derivative of a function, as a function, in its own right.

15.2Implicit differentiation
In this section we differentiate equations without expressing them in terms of a single
variable.
18.2Linear approximation
We use a method called ‘‘linear approximation’’ to estimate the value of a
(complicated) function at a given point.

curve.
31.2The First Fundamental Theorem of Calculus
The rate that accumulated area under a curve grows is described identically by that

variables can be separated on opposite sides of the equation.
