Displaying a Graph
When you press

, 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).
