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 ! and select Sequence. The app opens in Symbolic view.
The information below describes the major differences between the Sequence app and the Function app (see "Function,
Advanced Graphing, Parametric, Polar, and Sequence apps" on page 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.
You must set a non-negative integer starting value of N for each sequence. This value
is entered to the right of the first sequence value. 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
—Clears or selects a sequence for graphing and table-building
—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
—Resolves references when one sequence is defined in terms of another
Plot view Press P to display the Plot
view and see the graphs of the sequences
selected in Symbolic view. The functionality
here is the same as in the Function Plot view,
except that there are no Fcn functions.
Plot Setup view Press SP to display
the Plot Setup view. This view enables you to
configure the appearance of the sequence
This view offers the same options as the Plot
Setup view of the Function app (see "Function, Advanced Graphing, Parametric, Polar, and Sequence apps" on page 22), but
with two extra fields:
• Seq Plot—Lets you choose between stairstep and cobweb plots
• N Rng—Lets you set the range of terms to plot for each sequence
Also, there is no Method field.
Numeric view Press N to display Numeric view. This view is the same as you see
in the Function app.
