Hi !

I'm getting the following error when i run my script !!!!

Error, (in sqrfree) argument must be a polynomial or a rational function in {zB, TBA, yB, d, xB}

I'm using the sqrt function for my variables but it'S returning this error

Sample of my code

I have been wondering about the reception of an independent patch Library for Maple.

I'll lay out a few ideas, and then maybe some criticism (or indifference) might follow.

I'm a bullet-point sort of person:

• sourceforge project with a few willing experts for vetting and gatekeeping of submissions.
• Patch .mla Library archive, going into /toolbox/Patch/lib/ so as to get picked up automatically by libname.
• Self-building, with...

On his blog, Jaime Zawinski (of Netscape and XEmacs fame) relates a tale of finding limits in the (supposedly) unlimited big number representation on a TI Lisp machine in the early 1990s. It is an amusing story, and it makes me wonder if GnuMP is has a similar limit on a different scale.  Or in other words, is there a positive integer small enough to fit into memory  (assuming 64 bit address space) but that cannot actually be constructed in GnuMP due to limits in the implementation? Does someone here know enough about the GnuMP internals to give the answer?

I have been thinking about creating a Maple benchmark, to show a performance ranking versus operating system and hardware.

Is there any interest in such a thing?

If the results were put in a mapleprimes blog post, then they might be editable, and so could be updated as more items were submitted (messaged or emailed, to me, say).

After having Maple for a week I'm happy with it but still have to learn a lot about the kinds of problems it can solve.  Here is a problem I solved many years ago whose solution I have misplaced.  I'm wondering if Maple could help me recover my solution.

Write an expression for ab (a and b real) using only the unit (1) and the operations of adding, subtracting, and taking the reciprocal.

I'm also curious whether this is a well-known problem.  As I recall, I didn't find any references to it when I worked on it before.

Special Relativity has been around for ~100 years, General Relativity for ~90 years.  I'm hoping that with the assistance of Maple and Mapleprimes I may be able to do some tensor calculus to better understand Einstein.  Perhaps the twin paradox is within my reach.  Perhaps even the orbit of Mercury.

In the following worksheet, evalf[4997](... does what I expected and evalf[4998](... does not.

Something I've been wondering about...

i am solving a heat equations with maple but i didn't work out. if you guys can get it out plz give me code. thanx a million

diff(u1(x,t),t)=diff(diff(u1(x,t),x),x))-a*(u1(x,t)-u2(x,t))+b*(u3(x,t)-u1(x,t))
diff(u2(x,t),t)=diff(diff(u2(x,t),x),x))-c*(u2(x,t)-u3(x,t))+a*(u1(x,t)-u2(x,t))
diff(u3(x,t),t)=diff(diff(u3(x,t),x),x))-b*(u3(x,t)-u1(x,t))+c*(u2(x,t)-u3(x,t))

i need the expression of the u1(x,t)，u2(x,t)，u3(x,t) and the a,b,c are constants.

Looking forward to hearing from you!!!

I've just reformatted my computer and NEED to reinstall Maple 11 ASAP,
assignments are due soon.
I am having trouble installing it

1st time Installing)

   Everything was alrite until my cd-drive went haywire and the installiation frooze
   i then ended the task (task manager), maple as far as i know created the folder 
  program files, a few files there but NO WORKING PROGRAM is there leading to my second attempt to reinstall

2nd time installing)

"Maple 11 already installed"
  confused i decided to explore maple 11 folder, attempt an uninstall

Hello,

Another interesting undocumented package in the Maple 11.02 Library.

My oldest son, Stuart, recently completed a Science Fair project on sudoku puzzles. While I am fairly good at solving sudoku puzzles, the mathematics is something that is completely outside my area of expertise. After seeing the paper by Hurzberg and Murty in the Notices of the AMS (June/July 2007) and additional papers by Felgenhauer and Jarvis (http://www.afjarvis.staff.shef.ac.uk/maths/felgenhauer_jarvis_spec1.pdf)  and Russell and Jarvis (http://www.afjarvis.staff.shef.ac.uk/maths/russell_jarvis_spec2.pdf) and Jarvis' sudoku webpage (http://www.afjarvis.staff.shef.ac.uk/sudoku/), I felt that I had a reasonable understanding of some of the basic ideas involved in counting unique sudoku puzzles. While I had nothing to add to the mathematical ideas, I did see the potential to create a tool to visualize these ideas. The result is the worksheet I just uploaded to MaplePrimes:
