TI-83 Plus Parametric Graphing 161
Setting the Graph Format
To display the current graph format settings, press y .. Chapter
3 describes the format settings in detail. The other graphing modes
share these format settings; Seq graphing mode has an additional axes
format setting.
Displaying a Graph
When you press s, the TI-83 Plus plots the selected parametric
equations. It evaluates the X and Y components for each value of T (from
Tmin to Tmax in intervals of Tstep), and then plots each point defined by
X and Y. The window variables define the viewing window.
As the graph is plotted, X, Y, and T are updated.
Smart Graph applies to parametric graphs (Chapter 3).

You can perform these actions from the home screen or a program.
• Access functions by using the name of the X or Y component of the
equation as a variable.
