User Formulas
In addition to the calculator’s built-in formula, you can also input your own formulas for later
recall when you need them. You can also store built-in formulas under different names and
edit their contents if you want. Formulas you create and save under the name you want are
called “user formulas”.
Important!
A user formula actually is a program whose run mode is “Formula.” When performing the
following procedure also refer to “Program Mode (PROG)” (page 104).
A
Saving a Built-in Formula Under a Different Name
1. Press
G
to display the built-in formula menu.
• For details about this procedure, see “Using Built-in Formulas” (page 97).
2. Press
z
2
(Save formula).
• This will display the fi le name input screen, and
automatically alpha-lock the calculator’s keyboard
(
1S
).
3. Enter up to 12 characters for the fi le name and then press
w
.
• This saves the specifi ed built-in formula as a program (user formula) and displays the
Fmla List screen with the user formula you just saved highlighted.
