Course: Calculus III
Topic: Power Series
Subtopic: Calculus of Power Series

Overview

Now that we are able to write a variety of functions as power series, we can use the power series form of these functions to perform calculus processes such as finding limits, differentiating, and integrating. Doing calculus on the power series is often much easier than on the original function.

Objectives

By the end of this topic you should know and be prepared to be tested on:

• 12.4.1 Evaluate a limit by substituting the power series in for the function and finding the limit of it
• 12.4.2 Differentiate a function by substituting the power series in for the function and differentiating it
• 12.4.3 Solve a basic differential equation by substituting a power series in for the function and its derivative(s) and solving the resulting equation
• 12.4.4 Integrate a function by substituting the power series in for the function and integrating it
• 12.4.5 Approximate the value of a definite integral (to within a specific error) by substituting the power series on for the function and integrating it
• 12.4.6 Represent Real numbers using power series (eg. substitute x-values into a convergent power series to represent a familiar Real number such as pi)
• 12.4.7 Represent functions as power series (eg. given a power series identify the function it represents)

Supplemental Resources (recommended)

A worthy (and very cool!) expansion of this material, one with current applications in a variety of STEAM fields (science, technology, engineering, arts, mathematics) is Fourier Series. Lots of good reads on the web. I recommend that you at least read An Introduction to Fourier Series by Dale Hoffman (Bellevue College in WA) and Fourier Series Introduction from Interactive Mathematics.
