Before Drawing A Graph For A Recursion Formula - Casio fx9750G User Manual

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).
u u u u u 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
P.254 To specify the draw/non-draw status, use same procedure as that for specifying
generation/non-generation status.
u u u u u To specify the type of data to be plotted (Σ Display: On)
You can specify one of two types of data for plotting.
