Registering And Using Defining Equations For F(X) And G(X); Registering A Defining Equation - Casio fx-8200 AU User Manual

Equations for f(x) and g(x)
Registering and Using Defining
Equations for f(x) and g(x)
Your calculator includes "f(" and "g(" functions that you can use after
registering defining equations for them. For example, after registering f(x)
2
= x + 1 as a defining equation for the "f(" function, you can calculate f(0) =
1 and f(5) = 26.
Pressing displays a menu for registering the defining equation of f(x) or
g(x), and for inputting "f(" or "g(".
Note
• The defining equations of f(x) and g(x) are also used by f(x) and g(x) in the Table app.
For information about the Table app, see

Registering a Defining Equation

Example 1: To register f(x) = x
1. Press , select the Calculate app icon, and then press
2. Press , and then select [Define f (x)].
• This displays the f(x) equation registration screen.

3. Input x + 1.
4. Press .
• This registers the expression you input, and the screen that was
shown before you pressed
Note
• A defining equation can be registered from any calculator app except Distribution.
However, depending on the screen displayed by the calculator app (for example, if a
menu screen is displayed), the menu may not appear when you press
