Sequence 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.

Setting the Graph Mode

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

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.
