I want to ask a question, but I cannot submit it using the link below. I tried several times, but it didn’t work. I wrote it like this, but I didn’t get the desired answer.

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 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

Is there a way to use alternative plotting packages in Maple such as open source options: Plotly or Matplotlib?
