INTRO TO PROGRAMING:
EVALUATE A FUNCTION - HP 48

 

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 in a "table" format. This may be helpful when determining a reasonable window for graphing or investigating the value of a limit. Initially the table appears as a list of ordered pairs on the stack. Use the  key to view the table in matrix form. This allows you to scroll up and down through the table of values.
Anything in RED denotes a button on the calculator. For example + is the addition button.

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