Differences in Sequence and Function Graphing Differences in Sequence and Function Graphing Differences in Sequence and Function Graphing Differences in Sequence and Function Graphing
This module assumes that you already know how to graph y(x) functions as described in
Basic Function Graphing. This section describes the differences that apply to
sequences.

Use 3 to set
Graph = SEQUENCE before you define sequences or set Window
variables. The Y= Editor and the Window Editor let you enter information for the current
Graph mode setting only.
Defining Sequences on the Y= Editor Defining Sequences on the Y= Editor Defining Sequences on the Y= Editor Defining Sequences on the Y= Editor
If a sequence requires more than one initial value, enter them as a list enclosed in
braces { } and separated by commas. You must use a list to enter two or more initial
values.
You can define sequences u1(n) through u99(n).
Use ui only for recursive sequences, which
require one or more initial values.
Enter {1,0} even though {1 0} is
shown in the sequence list.
