Defining and Displaying Sequence Graphs
TI-83 Plus Graphing Mode Similarities
The steps for defining a sequence graph are similar to the steps for
defining a function graph. Chapter 6 assumes that you are familiar with
Chapter 3: Function Graphing. Chapter 6 details aspects of sequence
graphing that differ from function graphing.
Setting Sequence Graphing Mode
To display the mode screen, press z . To graph sequence functions,
you must select Seq graphing mode before you enter window variables
and before you enter sequence functions.
Sequence graphs automatically plot in Simul mode, regardless of the
current plotting-order mode setting.
TI-83 Plus Sequence Functions u, v, and w
The TI-83 Plus has three sequence functions that you can enter from the
keyboard: u , v , and w . They are above the ¬ , − , and ® keys.
