Pad Operation
(1) On the application menu, tap
(2) On the Graph Editor window, select the sheet and the line where you want to store the
built-in function.
(3) Tap
and then [Built-In].
(4) On the menu that appears, tap the built-in function you want to select.
• This displays a dialog box for assigning values to the coefficients. The actual
coefficients that appear (
(5) Assign values to each coefficient.
(6) Tap [OK].
Saving the Me
age Box Expre
You can save the expression currently displayed in the Graph window message box to the
Graph Editor window. This capability comes in handy when you want to save an expression
that appears in the message box while you are using the sketch function (see "3-6 Using the
Sketch Menu").
Note
• The following are the steps you should perform after an expression is stored in the
message box of the Graph window.
