16-3 Editing Tables and Drawing Graphs
You get a choice of four options for editing tables and drawing graphs.
• Deletion of a recursion formula table
• Drawing of a connect type graph
• Drawing of a plot type graph
• Drawing of a graph and analysis of convergence/divergence (WEB)
You can access these options from the function menu that appears at the bottom
of the screen whenever a table is displayed.
• {

• {
DEL} ... {table delete}
• {
WEB} ... {convergence/divergence (WEB) graph draw}
• {
G·CON}/{G·PLT} ... {connected type}/{draw plot type} recursion graph draw
• The {WEB} item is available only when a table generated using a formula for
linear recursion between two terms (
a
n
+1
=,
b
n
+1
=) is on the display.

Before Drawing a Graph for a Recursion Formula
You must first specify the following.
• Graph color (blue, orange, green) ............................... {BLUE}/{ORNG}/{GRN}
• Draw/non-draw status of for the recursion formula ..... {SEL}
• The type of data to be plotted .....................................
