TI-83 Plus Sequence Graphing 180
You can define sequence functions in terms of:
•
The independent variable n
•
The previous term in the sequence function, such as u( n N 1)
•
The term that precedes the previous term in the sequence function,
such as
u( n N 2)
•
The previous term or the term that precedes the previous term in
another sequence function, such as
u( n N 1) or u( n N 2) referenced in the
sequence v( n) .
Note: Statements in this chapter about u( n) are also true for v( n) and w( n) ;
statements about
u( n N 1)
are also true for
v( n N 1)
and
w( n N 1)
; statements about
u( n N 2)
are also true for
v( n N 2)
and
w( n N 2)
.
Displaying the Sequence Y= Editor
After selecting Seq mode, press o to display the sequence Y= editor.
In this editor, you can display and enter sequences for u( n) , v( n) , and
w( n) . Also, you can edit the value for nMin , which is the sequence
window variable that defines the minimum n value to evaluate.
