Archives: Casio Prizm (fx-CG) Math Programs
Currently viewing:

Casio Prizm programs for all versions of the calculator. Some programs designed for earlier versions (the CG10 and CG20) may not work correctly on newer calculators (the CG50). We have a guide for how to put programs on the calculator. Lua programs also need LuaZM to run.

## Files

1. ### Eigenmath

This is a port of the powerful Eigenmath math engine, by George Weigt, to the Casio Prizm, providing numerous math functions not originally available in these calculators, including symbolic computation. This port includes a function catalog, ability to create and execute scripts, draw graphs, and much more. All 100+ Eigenmath commands work. Output is pretty-printed whenever possible, and 200 lines of output are stored for scrolling at any time. Command execution can be stopped. The state of the add-in is optionally automatically saved when exiting. Source code and more info is available at: https://github.com/gbl08ma/eigenmath .

2. ### [Prizm] Graph3DP 1.1

Graph3DP is a powerful 3D graphing application for the Casio Prizm (fx-CG10/fx-CG20/fx-CG50). Enter one to six 3D equations, and rotate and zoom the resulting graph. You can adjust the window and trace over the mesh to examine X, Y, and Z value. This final 1.0 release has been thoroughly tested, and the underlying equation-parsing system, AHelper's gCAS2, has been overhauled for speed and correctness. Graph3DP understands thirteen built-in math functions, from sin() to atan() to sqrt() to ln(), plus addition, subtract, multiplication, division, grouping, and exponentiation. Give it a download and try it today; this will surely become an permanent fixture on your Casio Prizm.

5. ### Discriminant V.2

Updated file of Discriminant

This program finds the discriminant of a 2nd degree trinomial,
and solves for k in direct, inverse, and joint variation,

Soon to come:
Right now I'm working on turning this into an Add-in. So the next version will (hopefully) be in Add-in form.

7. ### Matrix 25+ 7400GII

Complete matrix calculation for Graph 25+Pro and FX-7400GII:

Invert (INVERSE)
Raise to higher power (M HOCH X)
Multiplication with scalar (M MAL X)
Multiplication with matrix (M MAL M)
Determinant (REFDET)
Gaussian elimination (REFDET)
Gaussâ€“Jordan elimination (RREF)

Editing
Copy matrix to other lists (KOPIEREN)
Generate a random matrix (M ERZEUG)

Input of matrices in then lists of the STAT-application, calculation in PRGM-application, result again in STAT-application.

8. ### ~MATH~

~MATH~ is just a simple program I made for the Casio fx-CG50 by combining all of the many math programs I'd already made to speed up the homework process. I basically made a program for everything I could when we learned it, so some of the functions in here will seem really random. Also, I'm only in Algebra 2, so don't expect anything mind-blowing. Also, I put a password on the program so that breaking (AC/ON) to exit wouldn't bring you to the source code. If you would like to view the source code, the password is "MATH"
