When using Maple 15, sometimes the pagackages and formulas that were previously defined seem to completely drop it.  I'll load packages and assign variables at the beginning of my project, yet after maybe 10 minutes or so, I have to redefine my variables and reload my pacakges.  I have noticed that it happens more often if I try to switch over to the "Text" tab and then back to "Math."  It's very intermittent, Maple will be working just fine churning out graphs,...

Hi, someone insert a .mw file in the mapleprimes answer, but i could not open it. May I know how do i open the worksheet please? It does not show when i click on it. I tried "save target as" it didn't work as well. Please help. Many thanks, Serena Lim

Hi All,


I am using maple 15 for a mechanical modeling, which has some very complex trigonomitry manipulations. The

script runs fine in maple 9.5.1 under window XP. But when I try to load the script in maple 15 under window 7,

it keeps loading forever. I noticed the memory usage in window manager to approach 1GB. (I have 4 GB in my PC).

The 9.5.1 uses much small portion of the memory. Does anyone see this problem before?

In which context runs subj? Why all time when i start debugging with 'stoperror' it stops at 'interface' call i.e. in debugger


doesn't return 3 as worksheet returns. It return interface('prettyprint') i.e. symbol.

That's the question... 'cause I've tried to open it using

./maple14/bin/maple -cw

like a thousand times and nothing happens...

I was solving one Math puzzle and found out a strange behaviour of the Optimization package commands in the Classic Worksheet.

Let us minimize the function 7*x+3*y under the constraint 6*x+2*y >= 49 for non-negative integers. When I type

Optimization:-Minimize(7*x+3*y, {6*x+2*y >= 49}, assume = nonnegint);

Hi all,

A while ago, I had asked a question relating to calling to an MapleSim .msim simulation within maple .mw worksheet. (Thank you Acer! :) I got it working but then another issue just popped up...The basic structure is as follows:


A := MapleSim:-LinkModel('filename' = "TriplePendulum_WORKS_v2.msim")

for z from 1 to 50 do


I've made exam questions for students that they have to answer by doing some calculations in Maple.

I would like to let them copy the commands they used to a Maple TA text field.

However, the standard worksheet in our computer lab uses 2-D math. Copying this 2-D math to Maple TA works fine with "paste as plain text", but copying 1-D math also works with ctrl-v in Maple TA, which is more convenient for students under stress.

Since I am not allowed change...

i just installed maple 15 in my macbook but i can't find classic worksheet, is it only for window?

Why does Maple Italicize every letter I type whenever I create a new file?

Is there a way to disable this automatic italicization?

Your worksheet may be incomplete"

Hi, I use maple 12 for mac, I have an exam at 9am, it's almost 3am and my whole exam notes (open "maple" exam, as opposed to open book) have just corrupted.




I'd like to read old Maple Worksheets created with Maple V release 4 (.mws files) to the Maple version 12.

When I am loading old worksheets, then system crashes with an error message:
Kernel connection lost, You should save this worksheet and restart Maple ....

Is there a way to load (import) old worksheets into newest versions of Maple

Hello, I'm trying to solve a very long system of equations, I've used PolynomialSystem and works, but it does not give me all of the solutions of the system. Im trying to do the solve comand, but after a few hours the mserver crasher and it needs to close, without having an output.

I woul really appreciate if anyone has a solution for this, I need to solve this and I'm getting stuck with this.

I'm attaching my worksheet
