kModify Function OperationsuTo modify a graph in the Graph mode

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

2.On the Setup screen, change the “Dual Screen” setting to “Off”.

3.Configure V-Window settings.

4.Specify the function type and enter a function that contains variables.

•In addition to manual input, you also can input expression containing variables using the built-in function type list that appears when you press 4(TOOL)3(BUILT-IN). The content of the built-in function type list is the same as that in the Dyna Graph mode (page 5-40).

5.Press 5(MODIFY) to execute the Modify function.

•This will draw the graph function you entered in step 4.

6.Use f and c to select Step (which will change its color to magenta) and then use the number keys to enter a step value.

7.Use f and c to select the variable you want to modify.

8.Use d and e to change the selected variable value by the unit specified by the step setting.

9.You also can enter the variable value directly.

10.To exit the Modify operation, press J.

Example

To register the graph expression y = x2 − Ax (A initial value = 0) and

 

specify a step of 0.5, and then observe changes in the graph as the

 

value of A changes from 0.5 to 2. Next, enter a value of −2 for the value

 

of A and observe how the graph changes. Use initialized (INITIAL) V-

 

Window settings.
