Defining and Displaying Parametric Graphs

TI-84 Plus Graphing Mode Similarities
The steps for defining a parametric graph are similar to the steps for defining a function graph.
Chapter 4 assumes that you are familiar with Chapter 3: Function Graphing. Chapter 4 details
aspects of parametric graphing that differ from function graphing.
Setting Parametric Graphing Mode
To display the mode screen, press z. To graph parametric equations, you must select
parametric graphing mode before you enter window variables and before you enter the
components of parametric equations.
Displaying the Parametric Y= Editor
After selecting parametric graphing mode, press o to display the parametric Y= editor.
In this editor, you can display and enter both the X and Y components of up to six equations,
and through and
