# Casio fx-7500G Software

Casio fx-7500g is a programmable pocket calculator. I wrote some programs for it, enjoy!

## Applications

- Linsys, 1.0: solves a linear system of N variables
- DFA simulator, 1.0: simulates a Deterministic Finite Automaton, a true/false decisor based on a symbol/state table
- Integral, 1.0: numerically solves the finite integral of a given function
- Routh, 1.0: calculates the Routh table of a (linear) dynamic system
- Fraction, 1.0: simple manipulation of fractions (including simplification)

## Games and drawings

- Mandelbrot fractal plotter, 1.0: it will take really long (=some hours) to plot the complete Mandelbrot fractal with this program, but the final result is amazing
- Gingerbreadman fractal plotter, 1.0: another fractal. Formula is easier than Mandelbrot's, so plotting is much faster
- Spirographic plotter, 1.0: a simple demo to draw spirographic curves
- Shooting game, 1.0: a small artillery shooting game on your calculator, very useful if today's lessons are deadly boring
