Activity Overview

Taylor polynomials associated with five common functions.


  • Produce various graphs of Taylor polynomials
  • Discover how the accuracy of a Taylor polynomial is associated with the degree of the Taylor polynomial
  • Visualize the accuracy and relate this to symmetry, arc length, and a point of discontinuity
  • Examine certain common functions and draw specific conclusions about the Taylor polynomial associated with these functions


  • Taylor polynomial
  • degree n
  • accuracy of the approximation
  • neighborhood of a
