Limit of Sin(x)/x

Published on 08/18/2010

Activity Overview

In this activity, students will graph f(x)=sin(x)/x in order to visually determine the limit as x approaches zero. They will confirm the answer numerically by tracing left and right limit points to capture values in a spreadsheet.

Key Steps

    In this activity, students will graph the function f (x) = sin(x)/xin order to visually determine the limit as x approaches zero.

    Students set up automated data capture and numerically investigate the values. In order to emphasize that for a limit to exist it must be approaching the same value from both sides, students will examine both sides of zero.
