Parametric Graphing

In this editor, you can display and enter both the
X
and
Y
components of
up to six equations,
X
1T
and
Y
1T
through
X
6T
and
Y
6T
. Each is defined in
terms of the independent variable
T
. A common application of parametric
graphs is graphing equations over time.
Selecting a Graph Style
The icons to the left of
X
1T
through
X
6T
represent the graph style of each
parametric equation (Chapter 3). The default in
Par
mode is
ç
(line),
which connects plotted points. Line,
è
(thick),
ë
(path),
ì
(animate), and
í
(dot) styles are available for parametric graphing.
Defining and Editing Parametric Equations
To define or edit a parametric equation, follow the steps in Chapter 3 for
defining a function or editing a function. The independent variable in a
parametric equation is
T
. In
Par
graphing mode, you can enter the
parametric variable
T
in either of two ways.

Two components,
X
and
Y
, define a single parametric equation. You
must define both of them.
