k k k k k Before Drawing a Graph for a Recursion Formula
You must first specify the following.
• Draw/non-draw status of for the recursion formula
• The type of data to be plotted
To specify the draw/non-draw status, display the Recursion Menu and then press
1 (SEL).

To specify the draw/non-draw status of a formula
There are two options for the draw/non-draw status of a recursion formula graph.
• Draw the graph for the selected recursion formula only
• Overly the graphs for both recursion formulas
To specify the draw/non-draw status, use same procedure as that for specifying
generation/non-generation status.
uuuuu
To specify the type of data to be plotted (
Σ
Display: On)
You can specify one of two types of data for plotting.
• a
n
on the vertical axis, n on the horizontal axis
•
Σ
a
n
on the vertical axis, n on the horizontal axis
In the function menu that appears while a table is on the display, press 5 (G•CON)
or 6 (G•PLT) to display the Plot Data Menu.
1 ( a
n
) ........... a
n
on the vertical axis, n on the horizontal axis
6 (
Σ
a
n
) .........
Σ
a
n
on the vertical axis, n on the horizontal axis
Example 1 Draw a graph of a
n +1
= 2 a
n
+ 1 with a
n
on the vertical axis and n
on the horizontal axis, and with the points connected.
Set the following parameters in the View Window.
Xmin = 0 Ymin = 0
Xmax = 6 Ymax = 65
Xscale = 1 Yscale = 5
6 (TABL) 5 (G•CON)
