Magnification in Maple worksheets and help pages...

Asked by: Jean-Michel 40
April 13 2025
2  4

hello everyone,

I am a bit shortsighted even with my glasses.

So my question is easy :: is there a way that when I open a (new) worksheet the magnification is 150%.

I can do it easily by hand but I am looking for 'something' in my maple.ini file to do this?

As well with the help pages.

Because even if I have a 150% magnification and I call a help page the display is still 100 % not 150%.

A part that I would like to set for every session a Digits:16 .

In the .ini file where I must input this? A ";" or not?

Thank you veru much.

Jean-Michel

ode dsolve series

I've reported this problem to Maple many years ago but still not fixed in Maple 2025.

Maple not able to verify its own solution on some series solutions using odetest.

Any one can suggest a workaround one can use other than odetest to verify ode solution when using series? Or have an idea why this happens?

The solution is correct but for some reason odetest returns FAIL 

Below is one example of many I have

In the File menu,  the Export As dialog is missing. Only the default (.pdf) can be used; no .mpl or .tex)
The Save As dialog is incomplete (e.g. save to .mws).

Or, is the installation corrupted?

Exploring the Mapping of Vertical Lines under 𝑤 ...

In the transformation w = e^z, vertical lines in the complex z-plane of the form Re(z)=a are mapped to circles of radius e^a in the w-plane.

Can I create a Maple visualization that does the following:

  1. Displays the result side by side, showing each vertical line in the z-plane and its corresponding mapped circle in the w-plane.

  2. Does it use a different color and style for each line and its image (e.g., dashed, dotted, solid, or different colors)?

Display quality with rotated screens...

Asked by: Anthrazit 885
resolution java orientation
April 09 2025

I need to take up an issue which is quite old, but still unsolved.

https://www.mapleprimes.com/questions/234249-Text-Quality-On-Screen

The problem is that in specific display configurations with one (rotated) vertical screen and multiple horizontal screens, the quality of fonts especially is significantly lower in Maple as with a configuration with just horizontal screens.

The affect is visible in Maple when it is on the horizontal (unrotated) screens.

Here are screenshots for comparision, and the layout of my desktop.

Screen layout:

Screenshot rotated

Screenshot unrotated

It seems that the problem is present when starting Maple. Changing the rotation of the screen when Maple is running does not affect the font quality in Maple.

Other (Windows) programs are not affected at all of this changes, so this seems to be a Java issue.

which method to use to remove RootOf ?...

Asked by: nm 11353

I know of 3 ways to remove RootOf, but sometimes they give different result. How does one decide which to use? This is done in code. So method to decide can't depend on looking at the screen and see which result one "likes" more than the other.

Is allvalues() the one to use all the time? Could one of these 3 methods fail, and then one has to try the next one?

Plotting Julia sets with Maple...

I am studying the Julia sets. I have tried the following two codes to generate Julia Sets. The first one I found in Maple Help, and the second one from http://ftp.informatik.rwth-aachen.de/maple/mfrjulfn.htm. I am wondering if there exists another code to generate the Julia set. My question is just for educational purposes, because those two codes work fine.

Maple 2025 - much slower than 2024?

by: JanBSDenmark 65 Maple 2025
April 07 2025

I teach math at the high school level.

I am worried that Maple 2025 appears to be slower than Maple 2024 - in particular for students with older, less strong laptops.

Maple 2025 takes 50% longer to start than Maple 2024 (or Maple 2025 Screen Reader which I expect to be using).

So, on more sluggist student laptops I fear the slowness overall will be an issue - in particular as Maple regularly has to be shutdown and restarted for some of those students.

Further, I really miss the "recompute section !" and the "magniffy" icons on the quest access bar. Having "recompute entire worksheet !!!" seems unwise though. I wish you could costumize the quest access bar.

Overall, from a teaching point of view, I am not at all impressed, sadly.

Hello,

Is there a special command in Maple (whatever the version) which returns all functions available?

ex: ?*sol* which at least will return solve,dsolve etc.

Thank you and kind regards to everyone.

Errors with formulas from the AI assistant with...

Just an observation.

I was wondering if less obvious errors than in the below can be avoided with future versions of the AI assistant. Maybe a warning that a formula uses special Maple symbols is possible.

Formulas without dimensions are more susceptible to undetected errors.

Deflection of a circular cantilever

(a first attemp with the AI formula assistant)

_local(I)

I

 (1)

AI prompt: Deflection of a circular cantilever with a  force applied at the end

Correct formular inserted ->
delta = F*L^3/(3*E*I)

delta = (1/3)*F*L^3/(E*I)

 (2)

AI prompt:  Moment of inertia of a circular cross-section

Correct formular inserted ->

I = (1/4)*Pi*R^4

I = (1/4)*Pi*R^4

 (3)

subs(I = (1/4)*Pi*R^4, delta = (1/3)*F*L^3/(E*I))

delta = (4/3)*F*L^3/(E*Pi*R^4)

 (4)

params := R = 25*Unit('mm'), F = 200*Unit('N'), L = 1.*Unit('m'), E = 210000*Unit('N'/'mm'^2)

R = 25*Units:-Unit(mm), F = 200*Units:-Unit(N), L = 1.*Units:-Unit(m), E = 210000*Units:-Unit(N/mm^2)

 (5)

subs(R = 25*Units:-Unit(mm), F = 200*Units:-Unit(N), L = 1.*Units:-Unit(m), E = 210000*Units:-Unit(N/mm^2), delta = (4/3)*F*L^3/(E*Pi*R^4))

delta = 0.1034759757e-8*Units:-Unit(N)*Units:-Unit(m)^3/(Units:-Unit(N/mm^2)*Units:-Unit(mm)^4)

 (6)

simplify(%)

delta = 0.1034759757e-2*Units:-Unit(m)

 (7)

NULL

The dimension of m^9 for a deflection clearly indicates an error.

A better prompt to avoid this error (caused by automatic simplification) could not be found

Download AI_formula_assistant.mw

P.S.:

This is a real example that happend to me where I did not notice the minus sign in Maples output in equation (1). The error  can easily be fixed by adding "local I" as the first statement of the document and the deflection becomes 1 mm.

New window is opened everytime...

Asked by: Scot Gould 1039
April 03 2025

Historically, when the Maple program is open and I double-click on a Maple document in my file manager (Windows), the document appears in a new tab of the open program.

With version 2025.0, I performed a completely clean install, deleting files and inheriting no properties from 2024. Now, when I repeat this process, a new window/program is created with the document appearing there. The document does not appear in another tab of the original window/program. Changing the option of sharing the same Maple math engine does not affect this unexpected behavior. 

Do others observe this behavior? Is there an option in one of the "Maple.ini" files that I could change? Or is this a bug?

I should note that this behavior is identical on multiple Windows 11 machines. The 2nd one was not a clean install.
