Local Linearity

Activity Overview

Visualize the idea of derivative as local slope.


  • Dynamically see the idea of "local linearity"—the behavior exhibited by a differentiable function when one zooms in on its graph.

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.
