Parametric Equations

Published on 06/09/2008

Activity Overview

We express most graphs as a single equation which involves two variables, x and y. By using parametric mode on the calculator you may use three variables to represent a curve. The third variable is t, time. (Topics - parametric functions)

Before the Activity

Students should have access to TI-83 Plus or TI-84 Plus.

During the Activity

Provide each student with a printed copy of the attached document. Students will use the graphing calculator to solve aprametric functions.

After the Activity

Review student results and, as a class, discuss questions that appeared to be more challenging. Re-teach concepts as necessary.
