Der Group,

 

after updating to OS X Yosemite the License data of Maple 18 are invalid. What can I do?

 

Yours

Berthold

1) Consider the followin Integral:

int(cosh(a*x)*cos(b*x),x)

How can I tell maple to give the results in terms of hyperbolic and harmonic funtions?
The maple returns the answer in term of exponentials with imaginary powers.
Also, I could not use the "simplify" command to turn the answer returned by maple into an answer in terms of what I want! Please see the code below.


2) Is there a way that I can update the maple integration database manaully?

Hello,

In a subsystem, i defined parameters like this in the "parameters" area :

 

In the "diagram" area, the parameters are not updated because i see this panel :

 

Do you know why the parameters are not updated (possibly only on visualization) ? And if yes, how i can do to visualize in this last panel the value of the parameters updated ?

Thanks a lot for your help

We have issued an update to correct a problem a small number of Mac and 64-bit Linux users have experienced when doing certain types of floating point computations on very recent hardware (such as this report on MaplePrimes: http://www.mapleprimes.com/questions/201815-Problem-Loading-MKL-In-Maple-18). When the problem occurs, instead of giving the result, Maple issues a “lost kernel connection” error message and must be restarted.

While this issue does not occur on most computers, we recommend that all Maple 18 customers running on Mac or 64-bit Linux install this update to ensure they do not encounter this problem. This update can be safely applied to any Mac or 64-bit Linux computer. Windows and 32-bit Linux users do not need, and cannot install, this update.

To get this update, you can use Tools>Check for Updates from within Maple, or visit Maple 18.01a Downloads.

I have a worksheet. I edit some variables' value. I then execute the whole worksheet to see how the graphs change. But the graphs generated by display command do not appear. All other calculations update fine. 

To overcome this. I save worksheet with my new variable values. Close the worksheet. Reopen it. Execute it. And now the graphs appear fine.

 

Yesterday afternoon, we updated MaplePrimes. The purpose of the update was primarily to squash some bugs and improve user experience.

Highlights of the update include:

  • The ordering of replies has been corrected, as described in this post by Carl Love.

  • We fixed a problem whereby some members were unable to attach a file to a question or post.

  • Flagging a comment now works correctly.

  • Broken images that were appearing on some of our older posts have been restored. In addition, some older posts had incorrect dates, and these have been restored.

  • Some embedded links to user profiles or messages were resulting in errors, and have been corrected.

  • After receiving a badge, members will now be notified via a pop-up message.


A number of other small improvements were made as well.

As always, thank you for letting us know when you encounter a problem, and please continue to do so. We take note of everything that you report, and we try our best to prioritize and take care of the issues.

Hello,

As a means of encoding information, I'm working with nested array objects (I had originally used lists, but they became too large and Maple suggested that I use arrays). The nesting should be at most four deep, but the nested arrays can have varying lengths. In order to work with the arrays, I have a series of procedures that manipulate a given array and update the existing array object to contain the result. The issue that I have is that one of my procedures needs to simultaneously use both the original array and a modified version of the array, but once the modification is performed, the original version no longer exists.

Ultimately, my issue boils down to this: is there a clean (or messy, I'm not picky) way to duplicate an array so that there are two copies of the array in memory? Just writting Array2 := Array1 just creates another pointer to the same array in memory from what I can tell, so that doesn't work. There is a function copy, but it doesn't seem to work on nested arrays. 

For example, running the following does not modify Array2.

Array1 := Array([Array([1, 2]), Array([3, 4])]);
Array2 := Array([Array([1, 2]), Array([5, 6])]);
copy(Array1, Array2);

Indeed, neither does

Array1 := Array([Array([1, 2]), Array([3, 4])]);
Array2 := Array([Array([1, 2]), Array([5, 6])]);
copy(Array1(2), Array2(2));

Unfortunately, the latter case would seem to mean that I can't just write a procedure to recurse through my layers of arrays and copy piecewise either.

Thanks in advance for any help.

Good morning to all our Mapleprimes members.

 

It is very helpful to many persons who are very passion and dedicated to teach Mathematics using Maple technology if the software package is loaded with updated maple procedures of all the topics.

I am being of them, request the technical authorities and the eminant professors to support and develop this requirement.It becomes an open door to many people to enter and aquire the immence knowledge in Maple.

 

 

With thanks & Regards

The board is going to work now with FF for me after latest updates.

NB: I got some mails advicing to delete (old) cookies for Mapleprimes, but
as my browser is alsways completely cleared on close (or on demand) that can
not have been the reason.

It works at least, if I give up all security settings. Which I do not want,
so I sketch a way to use them.

Be aware that not all in a page comes from Mapleprimes. Some is from another
server maplesoft.com and thus considered as 3rd party. Same for some scripts
and CSS etc, which stem from Google, jquery (or else)

If using NoScript or some blockers or similar essentially one has to allow
ajax.googleapis.com, which was needed in the previous version as well (see
below). Dito code.jquery.com is needed (both are 3rd party to Mapleprimes).

It still may hang up at loading ajax-loader.gif, which is located on the
server mapleprimes.com - I do not know why. After allowing a request policy
from mapleprimes.com to ajax.googleapis.com it loads.

That allows to still block all the social media stuff (especially FB connect
is disabled)

And currently I do not see calls to 2o7, just Omniture is trying to work.

---

For the call to Google: it seems to be needed only for their jquery library,
ajax.googleapis.com/ajax/libs/jquery/ and .../jquery/.

But the site calls the open source code.jquery.com/ui anyway. So why using
Google as well? Why not change and stay on code.jquery.com?

Calling to Google transmits my IP and browser header, it is like a fingerprint
and allows GG to identify me later on as Maple user. I dislike that very much.

Edited: edit works as well

Earlier today, we posted an update to MaplePrimes that introduces some improvements, and also addresses a few issues. The most significant & noticeable improvements are speed related, and the performance of virtually every function/page on MaplePrimes has been improved dramatically.  The average increase is approximately 2x, but some pages (for example, Recent Questions or Unanswered Questions) benefit from much greater increases!

Other issues/enhancements include:

  • There was a problem where MaplePrimes would occasionally send multiple notification messages when a single reply/comment/answer was added to a thread that you are subscribed to. This no longer occurs.

  • MaplePrimes has been added as a clickable option under 'products' when asking a question or creating a post, and MaplePrimes-related topics are now grouped together.

  • The lag between when a new thread is created and when it appears in the right-hand side bar (this lag was often multiple minutes) has been eliminated. 
     
  • We added a data-integrity restriction such that if an answer or a reply has been added to a message, that original message can no longer be deleted. Formerly, the original author was able to remove their post, and subsequently all related comments, at any time.

There were a variety of smaller issues corrected as well.

We hit a couple of small bumps in the road during the implementation of the update (for example, there was a temporary issue where replies or answers didn't work), but we believe these have been taken care of. If you encounter any additional issues, please let us know.

We hope that these enhancements and fixes continue to make MaplePrimes more enjoyable to use, and I'm looking forward to your feedback!

the seperate physics package update is a great welcome.  i wonder if the scientific constants paxkage could incorporate the same idea.  i can see why the elements properties were put there but it might have made more sense in the physics package.  anyways, the element proprties are continually being updated so it would make sense for small updates to occurr.  any thoughts.

Maple 16 update...

April 22 2013 eithne 860 Maple

Just wanted to let everyone know that the fix provided for the plotting problem discussed here is now available as a Maple 16.02a update.  This update will be available through Check for Updates and through the Maple 16.02a download page.

If there is a regression in an update it should be fixed within the same version and not left as an open bug in current versions.

Since 16.01 update is no longer available and 16.02 is the only option.  It would be very much appreciated by the mapleprimes community and maple users to see a 16.03 update.

I've several versions behind but I getting a strange behavior. I created an assignment using the eco0 question bank. Later this assignment was passed to a class a semester later. The question bank eco0 was updated. As the instructor, using the review button on the assignment shows the new version of the question bank. As a student, the assignments are getting the old question bank question.  The students didn't start the assignment until after the questionbank change.(I think I'm using version 4.0.) 

Based on past releases, after Dec 31 any hope of a 16.03 update becomes very very slim. 

You see, any last issued updates (back to Maple 11) have all happened before the turn of the new year.  And should we make it into the new year without one last update then we can almost be certain that Maplesofts focus is all on the next major release, Maple 17.

There is always hope, that a few more loose ends can be tied up before the next major release, however...
