. Chapter
3 describes the format settings in detail. The other graphing modes
share these format settings;
Seq
graphing mode has an additional axes

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).
Window Variables and Y . VARS Menus
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.
