IGraph Calculation DOT Switching Function

Use this function to specify drawing of all the dots on the Dynamic Graph X-axis, or every other dot. This setting is value for Dynamic Func Y= graphic only.

1.Press K(SET UP) to display the Setup screen.

2.Press AAA* to select Y=Draw Speed.

*fx-9750Gɉ: AA

3.Select the graphing method.

(Norm) … Draws all X-axis dots. (initial default)

(High) … Draws every other X-axis dot. (faster drawing than Normal)

4.Press ).

IUsing Dynamic Graph Memory

You can store Dynamic Graph conditions and screen data in Dynamic Graph memory for later recall when you need it. This lets you save time, because you can recall the data and immediately begin a Dynamic Graph draw operation. Note that you can store one set of data in memory at any one time.

STo save data in Dynamic Graph memory

1. While a Dynamic Graph draw operation is being performed, press

to change to the

speed adjustment menu.

 

2.Press (STO). In response to the confirmation dialog that appears, press (Yes) to save the data.

STo recall data from Dynamic Graph memory

1.Display the Dynamic Graph relation list.

2.Pressing (RCL) recalls Dynamic Graph memory contents and draws the graph.

9.Graphing a Recursion Formula

Important!

• The fx-7400Gɉis not equipped with the RECUR mode.

IGenerating a Number Table from a Recursion Formula

You can input up to three of the following types of recursion formulas and generate a number table.

•General term of sequence {an}, composed of an, n

•Linear two-term recursion composed of an+1, an, n

•Linear three-term recursion composed of an+2, an+1, an, n

1.From the Main Menu, enter the RECUR mode.
