# Chapter 15: Applications of Differentiation: Power Series

##

## Introduction

We can use the power of differentiation to introduce a new way to describe
functions and to relate it to the ways previously discussed. We first discuss
the notions of infinite series, and of convergence, and then use differentiation
in this context.
