fx-5800p: Creating a Custom Formula

fx-5800p: Creating a Custom Formula

Here is a short tutorial on how to create a custom formula for the Casio fx-5800p. The fx-5800p has a library of 128 formulas ranging in various topics from geometry to physics and engineering.

Creating an Original Formula:

1. Press [ MODE ]
2. Select 5 for Programming Mode
3. Select 1 for New
4. Give a name, no more than 12 letters or numbers. Symbols are not allowed.
5. At the File Mode screen, select 3 for Formula.
6. Type your formula. Use the y=f(x) format.
7. When you are done, press the [ EXIT ] key.

Tip: You can use lower case letters, Greek letters, and stylized letters in the formula. Press [ FUNCTION ], then 4 for ALPHA to get access to these characters.

Remember: Variables are one character length. The fx-5800p will execute implied multiplication when it executes two more consecutive variables.

Running Your Original Formula:

1. Be in COMP Mode. (MODE, 1)
2. Press the [ FMLA ] button. Select 1 for the Original type.
3. Select your formula, press [ EXE ]
4. Use the arrow keys to enter values or scroll the formula. When you are ready to compute, press [ CALC ].


And that is about all there is to regarding creating and calculating formulas on the Casio fx-5800p.

  1. Eddie, can you delete unused formulas that come with the fx-5800P to make room for the custom formulas you want instead?
