INTRO TO PROGRAMING:
EVALUATE A FUNCTION - Casio 9800

 

Introduction
The instructions for entering, running, exiting, and editing are the same for any program. The actual program on this sheet allows you to quickly evaluate a function. This may be helpful when determining a reasonable window for graphing or investigating the value of a limit.  
 
Information that is printed within {} is not typed into the calculator. Usu\ ally this contains instructions for finding a particular command. Anything in RED denotes a button on the calculator. For example + is the addition button. Anything in BLUE denotes a button on the calculator that requires hitting another button first. For example the QUIT command will appear here as QUIT because you need to hit the SHIFT button first.

Your calculator manual will be very valuable for finding the commands and buttons needed for programming. If you have misplaced yours, visit the Casio website to view a copy. Casio Manuals
