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-82 STATS 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.
