Hi,

I want to solve the equation shown in the image, along with its given conditions, using Maple and obtain the same results as in the image, but it does not work. Could you please help me?

Although several similar problems were asked many years ago (see, e.g., the section “Formal linear algebra” here), there appears to be no new progress so far. It is said that such functionalities exists in the Physics package, but I cannot find any corresponding examples. 
In short, can Maple at present calculate these examples in terms of symbolic array constructs completely automatically?

residue(z^3*cos(1/(z - 2)), z = 2);

                  3       1
         residue(z  cos(-----), z = 2)
                        z - 2

l notice the help document  asks me to increse the n，but the n of essential singularity is infinity

I wrote a simple expand command in Maple - expand(cos((u - 2*k)*x))

only to get the result

2*cos(x*u)*cos(x*k)^2 + 2*sin(x*u)*sin(x*k)*cos(x*k) - cos(x*u)

The presence of a squared term seems to indicate a bug??

I need to compute complicated numerical integral, and my Maple integration does not produce very stable results. Is the a way to do that on line? 

In the below I had to add the assumption x>=0 to get simplifications. Am I wrong with my interpretation that the other assumptions should have been sufficient?

We are looking for the smallest natural number n with the property that both the digit sum Q(n) of the number n and the digit sum Q(n + 1) of the successor of n are divisible by 5.

In Maple 2025.1, why don't all the hotkeys show up when I press the Alt key?

Maple 2025.0 is OK，but update to 2025.1 all the hotkeys don't show up when I press the Alt key.Why?

During a birthday party, the birthday child realizes: In 1968, I was the same age as the sum of the digits of my birth year. How old will I be now at the end of 2025?

(Please no AI solution)

In the decimal system, specify the smallest natural number k that begins with the digit 7 and has the following additional property:
If you delete the first digit 7 and write it at the end, the newly created number z = (1/3)*k.

My name is William Cheung.  I am a Snapdragon X AIPC product manager.  I am reaching out to inquire about the current and future compatibility of Maple on Snapdragon X Windows PCs, which run on ARM64 architecture. With the growing adoption of ARM-based systems in enterprise and academic environments—especially those powered by Qualcomm’s Snapdragon X Elite platform—we are evaluating software solutions that can run efficiently on these devices.

Could you please confirm:

1. Whether Maple, as a commercial product, currently supports Windows on ARM (either natively or via emulation)?
2. If not, is there a roadmap or timeline for ARM-native support?
3. Are there any known performance or compatibility issues when running Maple on Snapdragon X PCs using Microsoft’s Prism emulation?

Note that I have successfully installed and run Maple 2025 with sample worksheet files on my Snapdragon X Windows PC.

Thank you for your time and assistance. I look forward to your response.

Hello, I am struggling with a Maple Flow document that has gotten a too large to manage - maybe around 100 printed pages of relatively straightforward calculations, basic plots, etc. - nothing exotic or what should be computationally intensive.  The worksheet takes a long time to load, if it loads at all, is prone to freezing and requires force quitting of the OpenJDK Platform binary when this happens, and oftentimes generates a kernal connection error:

So, in short, lots of issues that make usability a challenge. The document is easily broken into smaller sections, which I would prefer to do anyway. I have attempted to use the RunWorksheet command and can more or less get it to work for very simple cases:

However, the output is not ideal in that it includes the variable string. This command also doesn't appear to pass custom-defined units. The other issue is that when I test this same syntax on a fully-developed, formatted, etc., Maple Flow worksheet, I get invalid input warnings and can never get any values returned.

Ideally, what I would like to do is call a variable defined in one Maple Flow worksheet and have it be immediately usable in another Maple Flow document, or at least usable with some minimal processing. If anybody has any ideas, I would appreciate it.

Thanks

Hello, I am trying to get the Maple Flow add-in for Excel working and am following the step-by-step directions in Chapter 7.3 of the Maple Flow manual. My computer meets the requirements listed in Chapter 7.2.

After selecting the WMIMPLEX64.xla file as directed in the procedure, I get the following error in Excel:

The Excel toolbar also does not show the same six icons in the add-in toolbar that are shown in the Maple Flow manual (see the manual excerpt below); it appears that the missing icon is the key icon that would initiate the Maple Flow worksheet wizard.

If anybody has been able to get this to work or has suggestions to resolve these errors, I would appreciate any advice.

Thanks

Hello Maple Community,

I'm working on solving a PDE system for fluid flow in an L-shaped cavity (similar to previous work on H-shaped and square domains ) recently asked by some one here. I've implemented the governing equations in Maple but need help generating contour plots.

I'm attaching:
1. My Maple worksheet l_shape_cavity.mw
2. A PDF with the problem description and equations L_shape_cavity_work.pdf

The main issues I'm facing are:
- Setting up proper boundary conditions for the L-shaped domain
- Generating contour plots for velocity and pressure fields
- Ensuring the solution converges properly

Could you please help me with:
1. Correct implementation of the L-shaped domain geometry
2. Generating proper contour plots
3. Any suggestions for improving the numerical solution

Thank you for your assistance!

In Maple 2025 we are having problems with units.

In Maple 2024 we did not see same errors. Maple sheets working with Maple 2024 does not run in Maple 2025.

In Maple 2025, some units which are f.x. obviously 'J' is not recognices as 'J'.

In Maple 2025, part of units dissapears from expressions.

Just an example; the function v(t) below has correct units m/s, but when using simplify, the unit is changes to m
