How to define rules on a CAS calculator:
A rule can be defined to make it more efficient to work with them on a CAS calculator.
To define a rule on the CASIO ClassPad II:
A rule can be defined to make it more efficient to work with them on a CAS calculator.
To define a rule on the CASIO ClassPad II:
- Type the rule into the Main Menu.
- Highlight the rule → Interactive → Define.
- Name the rule (function) using using a letter from the abc keyboard.
- Check that teh correct variable is listed (use var keyboard to change).
- Press OK and the screen should display "done".
