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.
•{FORM} ... {returns to Recursion Menu}
•{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 (
an+1 =, bn+1 =) is on the display.

uTo delete a recursion table
1. Display the recursion table you want to delete and then press 2 (DEL).
2. Press 1 (YES) to delete the table or 6 (NO) to abort the operation without
deleting anything.

k Before Drawing a Graph for a Recursion Formula
You must first specify the following.
• Graph color (blue, orange, green)
• Draw/non-draw status of for the recursion formula
• The type of data to be plotted
To specify the graph color and the draw/non-draw status, display the Recursion
Menu and then press 1 (SEL+C) to display the following menu items.
•{SEL} ... {draw/non-draw status}
•{BLUE}/{ORNG}/{GRN} ... {blue}/{orange}/{green}
