To display the current graph format settings, press y
[FORMAT]. 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.
When you press s, the TI-83 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.
• Store parametric equations.
• Select or deselect parametric equations.
• Store values directly to window variables.
