Will Maple 12 run on 256 Mb's of RAM?  The website says 512 recommended but it doesn't give a minimum.  Can't go to 512 Mb's on my old laptop, the 8100 Toshiba Tecra memory slot B is failing (can't get it to work, one fix was to push on the RAM, doesn't help)  I know this isn't the place for it but if anyone has any tips or pointers to fix the RAM slot I would greatly appreciate it. 

Back to the original question does does Maple 12 work with 256 Mb's of RAM?

I am having problems animating the trajectory of an object in 3-D. I have no problems displaying the 3-D background and the trajectory of the objects, but I can't display the background and the animation of the object's trajectory in the same 3-D plot. The plot command that I am using is:

display(Pobj,Pline1,Pline2,...,orientation=[-45,45],view=-20..20,-15..15,0..5);

where

Pobj:= animate3d(odeplot(res1,[x(t),y(t),z(t)],0..5),-20..20,-15..15,0..5,color=black,frames=50);

BesselK(0,r)*r is being turned into something that gives wrong results.

The limit as r->0 is given as -1/2 when it should at least be positive.

Hi again

Seems I mostly post after an upgrade! This time I've two errors. The first is this message on startup: "Error, cannot raise the datalimit above the hard limit"

Which is meaningless to me unfortunately.

The second is the fact that I've no help files that can be accessed. Starting the old-style GUI gives a hint that the help database cannot be found but the *.hdb files do exist and in the sample location in the maple 12 install as in the Maple 11 install.

Any ideas?

TIA Tim

Hello everbody.  It's been a while.  I apologize for such a long absence.  Life gets busy, and I think we all know how that can be...

We hadn't been using Maple 12 for a full hour before we found a major bug.  To see / reproduce this error:

I have been trying to discover the difference between 2D Math and 2D Input. Help details /how/ to use them but not /why/.

I enter material as 2D Math, and sometimes it gets changed to 2D Input.

Hi everyone, I'm new here.

I'm using Maple 11 on vista... everything works fine, except I can't print.  When i hit page setup, print preview, or print, the program just freezes up.  I can't seem to get it fixed.

Help please?

I have tried to find something in Help that describes the difference, but no luck. I found that many of the math items that I entered were 2D Input, yet when I toggle using F5, I get Text <> 2D Math. How did I wind up with 2D Input? Copying and pasting?

Good morning.

Can anyone tell me why the legends are showing up today when they were not yesterday?

...and I intermittently get Plot Builder dialogs when I edit the commands associated with these two plots...

...Maple 12 seems unstable and unpredictable...is contant rebooting of Windows necessary when using the doc mode?

To help me learn Maple 12, I decided to translate a small project that I did into Maple.

1. Why is there an error in my text field at the beginning of the doc?

2. When I apply a new style to a paragraph, all the text changes to plain text: all formatting is removed. Is there a way to simply change the style and not the formatting, such as Italic?

3. I tried to follow the instructions in one of the training videos on how to hide math. As you can see, the assignment to d is still visible. Can simple assignments be hidden?

What is the right code to produce a sequence of iid NegativeBinomial random variables with Statistics package? It seems the natural choice only works correctly for size parameter equal to one when combined with Sample, though the theoretical moments are always correct. What's wrong with my code? Pls see http://www.mapleprimes.com/files/7371_NBD-problem.mw Thanks heaps.

I just installed Maple 12 (Home User version).  The first thing I checked was whether Maplet Builder is still part of Maple.  It is.  Then I checked whether, having built a maplet with Maplet Builder, you can run it from within Maplet Builder.  I saw the same behavior as in Maple 11:  You are out of luck if your maplet contains a MathMLViewer window--you have to save the maplet and run it standalone to see it run.  In other words, no change in Maple 12.  This may discourage people from using Maplet Builder, but I have a feeling Maplesoft may not see that a

Sloane's On-line Encyclopedia of Integer Sequences has the following entry:

A110375  Numbers n such that Maple 9.5, Maple 10 and Maple 11 give the wrong answers for the number of partitions of n.   
 
 11269, 11566, 12376, 12430, 12700, 12754, 15013, 17589, 17797, 18181, 18421, 18453, 18549, 18597, 18885, 18949, 18997

I wonder whether that can be extended to Maple 12 as well (I don't have it to check.)

In the Table Properties dialog, I was at first puzzled at the % field. Mine says 00.0% = 675.8 Points. Wasn't until I thought to modify the % box that I found that the 00.0 is really 100.0.
