I was fortunate enough to spend the last two weeks on vacation in the south of Spain. Spain is a country composed of intricately layered history and traditions; influenced over thousands of years by its various inhabitants and conquerors: the Phoenicians, Greeks, Romans, Visigoths, Moors, and of course the Christians (the Reconquista ended with the surrender of Granada in 1492 to Ferdinand and Isabella, the same year Christopher Columbus made his famous journey). Its food, music, art, architecture, and customs display these intertwined influences in unique and sometimes surprising ways.

Hi

I installed Maple 12 on Windows XP Sp3 and activated it. Maple 12 starts without any problem. When I want to evaluate an expression, context menu doesn't open. Cursor stay busy a moment and return normal. I have already installed Java Version 6 Update 10. Maybe, java version I have installed caused this problem. But I'm not sure. Can anyone tell me how to fix this problem. 

I am trying to export a plot object generated by implicitplot3d, for use and manipulation without Maple.  I am using Maple 11.02 (10/11/07) on Windows XP.

I therefore seem to have three choices:

1. POV.  My exported object does not render in pov-ray v3.6.

2. DXF.  My exported object does not read in TrueView, and reads as black in SolidWorks eDrawings and another freeware viewer.

Hello,

I have activated 2 times Maple 12 and I have tried to activate it a third time on my new computer but it doesn't work:

There is this message: the maximum number of activations has been reached.

Must I buy Maple 12 again?

As some expressions involving 'floor' and 'ceil' did not simplify as I have expected, I have gone to basics. In ?trunc > Description it is stated:

ceil(x) = -floor(-x)

But 'simplify' does not seem to know about this equation as this expression should simplify to 0:

simplify(ceil(x)+floor(-x));

                         floor(-x) + ceil(x)

In principle, this seems to be a weakness in 'simplify'. For comparison, in Mathematica 5:

Hey,

I've a problem with my maple version right since some time.

Every time I want to print the printing dialog states in the status line of the printer: "No jobs will be accepted" (this is freely translated from german).

also piping the output into a file doesn't work, it simple doesn't create that file.

If I start xmaple in a shell I got this:

Has anyone tried the technique used here, to run Maple 12's 32bit Classic GUI with the 64bit Maple 12 kernel binaries, on Linux?

Should I try and update it to work with Maple 11 or 12?

It looks like some symlinks would have to change or be added, relative to the way that I did it for Maple 10.

Has anyone ever tried to do a similar thing on 64bit Windows?

How do I send a message to the author of an entry?  Presumably I can click the "Send message" link in the Navigation pane on the left side of this website, however, doing so means that I have to first figure out what the "handle" is for the person I want to contact.  Previously there was a "send message to author", or something equivalent, link in each of the posts; has that gone away?

In this post I would like to kindly ask users of this package (if there are any) for a feedback. Please, add a comment to share your experience with FourierTrigSeries package (how do you use it) and suggest new features or report bugs.

Yesterday  the Maple 12.01 update installed on my computer.

Today, Maple 12.01 Standard does not start. Nothing happens, And after many minutes, nothing continues to happen (Douglas Hofstadter).

Maple 12.01 Classic starts--really fast.

Maybe it's the update. The other intervening factor was the very recent critical Windows secruity update.

Does anybody have a similar experience?

  Int(phi(u-a*I)*exp(k*u*I),u = -infinity .. infinity);
  Change(%, u-a*I = s, s); subs(s=u,%): expand(%): combine(%,exp);

                   infinity
                  /
                 |
   ...

The following would appear to be a pretty straightforward improper integral for Maple to handle:

q := Int( 1/x^p, x=1..infinity );
                                /infinity      
                               |          1    
                               |          -- dx
                               |           p   
                              /1          x    

Things start of well, with Maple recognizing that the answer depends on the value of p:

value( q );               # fine
                         /   (-p + 1)                  \
                         |  x         - 1              |
                    limit|- -------------, x = infinity|
                         \      p - 1                  /

The first case is when p>1:

value( q ) assuming p>1;  # good
                                      1  
                                    -----
                                    p - 1

The other case should be for p<1:

value( q ) assuming p<1;  # say what?
                            infinity p - infinity
                            ---------------------
                                    p - 1        

Maple 12.01 is now available. The Maple 12.01 update includes enhancements in a variety of areas, including:

• Differential equations and differential algebraic equations: Numerous enhancements to performance of numerical solvers
• MATLAB link: Extended to include support for MATLAB 2008b
• Language packs: Updates for Spanish, Brazilian-Portuguese, Greek, Japanese, and Chinese
• Plotting:
  • Improved behavior in plot3d when using numpoints and grid options
  • The plots[display] command now handles dual-axis plots inside array plots
• Graph Theory: Context-sensitive menus updated to include more graph theory commands
• Other improvements were made in:
  • Numeric integration
  • Physics package
  • SolveTools package
  • ArrayTools package
  • Debugger

Modern software tools should allow engineers to design, develop and test their designs before a single part is sent to the prototyping shop. So why is it not happening? Why are hundreds of prototypes manufactured, tested and then rejected? Why is so much time wasted at the testing and then redesigning stage?

Individually, the components for the ideal virtual prototyping tool are available, but they have not yet been wrapped up into a single integrated environment that’s based on design principles that engineers find intuitive.

Why is that?
