Watch these video lessons to understand Taylor series and the various types of functions which can be evaluated using them. Complete the self-assessments to gauge retention of key topics.

## Taylor Series - Chapter Summary and Learning Objectives

The lessons in this chapter explore how a function's derivatives can be used to express its infinite sums. Taylor series are a versatile tool for evaluating and computing series, so every lesson here deals with a certain aspect of Taylor series and its offshoots. Complete the video lessons and assessments to boost your understanding of series calculations in calculus. In this chapter our instructors discuss:

• The definition and formula for Taylor series
• Coefficients and polynomials of Taylor series
• Evaluating functions of a complex variable and polynomial approximation with Taylor series
• The definition and formula for Maclaurin series
• Interval and radius of convergence with Power series
• Assessing Taylor polynomials using the Lagrange error bound

Video Objective
