Someday (maybe) we will also include online access to other systems such as:

Open Source Systems

Maxima
See: http://maxima.sourceforge.net
Yacas
See: http://yacas.sourceforge.net/yacas.html
Reduce
See: http://reduce-algebra.sourceforge.net

Commercial Systems

Maple
See: MaplePrimes?
Mathematica
See: http://www.wolfram.com/products/mathematica/index.html
MathCAD?
See: http://www.mathsoft.com/solutions/calculation_management_suite/mathcad.asp
Mupad
See: http://www.mupad.de

Well, if you have Maple and Mathematica, you should have Derive too. :)

http://www.derive.com/

We do not have any commerical software on MathAction. I did approach both MapleSoft? (Maple developers) and Wolfram (Mathematica developers) to see if they would provide a copy of their software and allow us to integrate it here on MathAction. But so far Maplesoft has officially (but respectfully) declined and Wolfram did not even reply to my email.

Apparently Derive is only available for Windows systems. Development of Derive seems to have essentially stopped.

How much does Derive cost? What are it's significant features compared to Axiom? Maple? Mathematica?

List price for Derive is about $200US and student price is about $100US. Its core-level mathematical capabilities are equivalent to nearly every "general" CAS out there, and anything you can implement in them can be implemented in Derive. I have never been able to afford Maple or Mathematica or even Reduce, so I can't comment on them.

Ease of use: Derive is much easier to use than Maxima, although I think that's just because I've been using Derive since about 1994 (on DOS back then!). I just started with Axiom, so I can't comment on it either. Axiom has a great reputation on the "gentoo-science" mailing list, so I'm learning how to use it.

Development does appear to have slowed down
I wouldn't say stopped. The release level is 6.1. A couple of years ago, the founders of Soft Warehouse sold the business to Texas Instruments, so the business decisions are made now by TI rather than the founders as near as I can tell. In any event, Derive is essentially "complete" -- its main market is students.

I haven't found anything it can't do in a professional environment, though. My needs for a CAS right now are mostly to deal with equations in computer performance modeling -- Markov chains, ODEs?, Laplace Transforms, etc. Derive handles them well and was my only practical alternative on Windows systems until I got a working Maxima port a year or so ago. But if you need Grobner basis calculations, well, they have that too ... :)
