Plot Setup View
Press
SP
to display the Plot Setup view. This view enables you to
configure the appearance of the parametric graphs.
This view is similar to the Plot Setup view of the Function app (see page 20), except that it also
contains
T Rng
and
T Step
fields. These fields enable you to specify the range and fineness of the
t
-values used to generate the (
x
,
y
) points for graphing.
Numeric view
Press
M
to display Numeric view. This view is the same as you see in the
Function app.
Polar App
The Polar app enables you to define polar equations and explore their graphs and tables of
values. It is similar in structure and functionality to the Function app. To open the Polar app, press
I
and select
Polar
. The app opens in Symbolic view. The information below describes the major
differences between the Polar app and the Function app (described on pages 18 to 22).
Symbolic view
The Symbolic view of the Polar app enables you to specify up to ten polar
equations, each one defining
r
—the signed distance a point is from the origin: (0,0)—in terms of
, the anti-clockwise angle a segment from the point to the origin makes with the polar axis. An
example is
r
= (3
)/
.
The menu items are the same as in the Function Symbolic view, except that here
replaces
(and enters
when
tapped).
Plot view
Press
P
to display the Plot view and see the graphs of the equations selected in the
Symbolic view. The functionality here is the same as in the Function Plot view, except that there are
no
Fcn
functions.
