walterzorn.com— Of course, you have to know what the functions are and how to use them if you want it to work. Charting 1+1 isn't that much fun.

It's not a bad graphing package for basic functions - but it has none of the "special functions" predefined.(No Legendre polynomials, no Bessel functions of any kind [i.e. J's, Henkel, Neumann, etc]... No Dirac delta function, no Heaviside function, and no way to define piecewise functions)In short - it wont replace Mathematica, Maple, or Mathcad - but it's good for a quick graph or two.
I just finished a course in MatLab and I must say... it takes some time to learn but its really the best out there it has support for OOP, can work with images movies, sound, integrates with windows applications, and so on...
"Of course, you have to know what the functions are and how to use them if you want it to work. Charting 1+1 isn't that much fun."I love TFS. Diggers are f**king retarded!
I think 3d graphs, complete function support, and far easier modification pwn the crap out of the web applet - and besides, you can do a large amount of other math with a TI-89 :P
@pornelI'd hate to burst your fan-boy bubble, but I am forced sometimes to use grapher in a production setting and its frankly terrible. the only way in which anything it produces is useful for anything other that plotting equations faster than a TI-83, is if you fix the graphs up in photoshop first, (which adds way to much time to production).

Try: sqrt(4-(2-abs(x))^2); - sqrt(16 - 4 * abs(x))

God!!!! I HATE standard form!
