What Are the Best Free Alternatives to Texas Instruments Graphing Calculators?

[dimensionless]

I know there are programs like Octave and Scil-ab, but Octave needs Linux/Cygwin and the last version of Sci-lab I installed had super-slow graphics. Are there any smaller and more simple programs out there? All I'm really looking for is the functionality of a Texas Instruments graphing calculator.

This is a good question. I'd suggest looking at http://www.download.com/" , they might have something...

I was going to recommend this but you need to own a calculator to legally be able to use a ROM.

If you're just going to download a ROM or upload a friend's then you might as well pirate Mathematica or some other software that's not free so it becomes "freeware".

Its not as powerful as maple/mathematca etc...but its bloody fantastic for a free CAS
