Plot Setup view
Press
SP
to display the Plot Setup view. This view enables you to
configure the appearance of the polar graphs. This view is similar to the Plot Setup view of the
Function app (see page 20), except that it also contains
Rng
and
Step
fields. These fields
enable you to specify the range and fineness of the
-values used to generate the points for
graphing.
Numeric view
Press
M
to display Numeric view. This view is the same as you see in the
Function app.
Sequence App
The Sequence app enables you to define sequences. You can then view a stairstep or cobweb plot of a sequence, and explore a
table of sequence values. To open the Sequence app, press
I
and select
Sequence
. The app opens in Symbolic view. The
information below describes the major differences between the Sequence app and the Function app (described on pages 18 to
22).
Symbolic view
The Symbolic view enables you to specify up to ten sequence definitions in
n
.
Each sequence is defined either explicitly in terms of
n
or recursively. Note that
n
must be entered
as an uppercase character (
N
) in this app.
The menu items available depend on the equation you are specifying at the time:
•
: makes the selected definition editable
•
: deselects or selects a sequence for graphing and table-building
•
,
,
,
: enters the corresponding text when tapped
•
: cancels the current addition or change
•
: accepts the current addition or change
•
: displays the selected sequence in textbook format in full-screen view (with vertical and horizontal scrolling enabled)
•
: resolves references when one sequence is defined in terms of another
