Chapter 10 Introduction to the Derivative The concept of a derivative takes up half the study of Calculus. A derivative, basically, represents rates of change. 10.1 Limits: Numerical and Graphical Approaches Rates of change are calculated by derivatives, but an important part of the definition of the derivative is something called a limit.
