Calculus: Local Linearity
by Texas Instruments - Action Consequence, TI Math Lesson

Published on December 04, 2011

Objectives

  • Dynamically see the idea of "local linearity"—the behavior exhibited by a differentiable function when one zooms in on its graph.
  • Students will reason abstractly and quantitatively. (CCSS Mathematical Practice)
  • Students will construct viable arguments and critique the reasoning of others. (CCSS Mathematical Practice)

About the Lesson

The Local_Linearity.tns TI-Nspire document provides a tool for visualizing the idea of derivative as local slope by providing a dynamic zooming box that maintains square scaling between the x and y values.
