### Introduction

In Section 11.1 you were introduced to the idea of a derivative and you calculated some derivatives from first principles. Rather than calculating the derivative of a function from first principles it is common practice to use a
**
table of derivatives
**
. This Section provides such a table and shows you how to use it.

#### Prerequisites
