I've sure have heard of it, I just finished (about a month ago) porting
Maple 4.0 to the Amiga.

Maple is a product of the Symbolic Computation Group at The University of
Waterloo (of which I am a student).

For those who don't know about Maple or other such languages (e.g.  MACSYMA,
REDUCE, etc.)  Maple is capable of working with arbitrary length integers,
and performing exact rational arithmetic.  In addition to this, Maple
can work with "symbols" to perform operations on algebraic expressions
for instance you could type:

# differentiate x squared with respect to x
>diff(x^2,x);
					2 x

# integrate the previous result wrt x
>int(",x);
					 2
					x

# compute a big number  (720 factorial)
>720!;
		< you get lotsa output >

I could post a sample session if there is interest.

Anyways, Amiga Maple comes on 5 disks

	1  -- executables
	3  -- libraries
	1  -- help files

You can get (for the cost of the media) 5 more disks

	3  -- library sources
	2  -- Maple tests + test results

It is an EXTENSIVE (can you say BIG!) expandable system.  Most of Maple is
written in Maple, it is this portion that you get in the library sources.
You don't get the sources to the kernel.

You need at least 1.5 megabytes of total memory if you want to do meaningful
computations with Maple.  You don't need a hard disk drive (I *ported*
it without using one) but it does make your life easier.  If you don't
have a hard disk drive then 2 floppys are a MUST.  It's not protected so
you can make backups to your hearts delight.  Needless to say if you
install it on your hard drive it will take up a wholesome amount of
space (you have to copy the 5 basic disks to the drive, plus the sources
if you want to modify the libraries as well as doing your own programming). 

I beleive that Fred Walter had the prices right ($580, 1/2 off for educationals
sales) but I'm not sure.  I try to remain ignorant of these things.

Feel free to mail me questions about the Amiga version, if you have questions
about Maple in general you might be better off sending them to:

	maple@watmath.waterloo.edu

If you have very specific questions like "how does the difforms package handle
polynomials whose degree is an unknown" I'll just shrug and pass them along to
someone who knows better...
