I can't find the help page for Abel second kind, class B. 

Maple has help page for Abel second kind, class A and Abel second kind, class C. But not for class B. 

Here is an example of Abel second kind class B

ode:=(3*t*y(t)+y(t)^2)+(t^2+t*y(t))*diff(y(t),t)=0;
DEtools:-odeadvisor(ode)

I wanted to know the difference and the transformation used for class B to make it Abel first kind.

I googled and can't find it. Also local help skips over class B.

Is this documented somewhere else?

btw, find error on the help page for class A. Transformation used is wrong. Will leave this for another question.

I have repeatedly seen this on two Windows PCs:

The assignement operator := is rendered as a roman d

This happens after using Maple for some time.
 Exiting Maple and restart of Maple is required. Has someone noticed the same?
All on Windows 10 and for sure in screen reader mode (my default, cannot report on the new GUI).

It seems that the new Ribbon interface has several bugs (probably an update will come soon). So, not only the Export As is not working, but I see that (at least in Windows), opening a worksheet with a large output will display the output using the Maple input font.
Just save a .mw with the content:

expand((x+1)^200);

and then open it.

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.

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

ode:=x*diff(y(x),x$2)+y(x)=0;
IC:=y(0)=1;
maple_sol:=dsolve([ode,IC],y(x),'series');
odetest(maple_sol,[ode,IC],'series','point'=0);

x*(diff(diff(y(x), x), x))+y(x) = 0

y(0) = 1

y(x) = c__1*x*(series(1-(1/2)*x+(1/12)*x^2-(1/144)*x^3+(1/2880)*x^4-(1/86400)*x^5+O(x^6),x,6))+ln(x)*(series(-x+(1/2)*x^2-(1/12)*x^3+(1/144)*x^4-(1/2880)*x^5+O(x^6),x,6))+(series(1-(3/4)*x^2+(7/36)*x^3-(35/1728)*x^4+(101/86400)*x^5+O(x^6),x,6))

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?

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)?

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.

With the new GUI:
I get all files (*.*) listed by default.
Other file types to filter are not listed.

Is this the same on other machines?

Can I do something about it?

I'm struggling to find the Undo botton, according to the help file they should reside under "View" menu - select Toolbar.

I can't find any "Toolbar" in the View menu.

How do I make indents in Maple 2025 for more readable layout?

Haven't used that much in 2024, but according to help this should be in Format - Tab settings. I don't find that in 2025 unfortunately.

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?

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.
 

with(Fractals:-EscapeTime); with(ImageTools); bl, ur := -2.0-1.5*I, 2.0+1.5*I; c := -1; J := Julia(700, bl, ur, c, cutoff = 4, iterationlimit = 6000, output = layer1); Embed(J)

restart; julfn_zsqrd := proc (x, y) local c, z, m; c := evalf(0); z := evalf(x+I*y); for m from 0 to 50 while abs(z) < 2 do z := -z^2+z end do; m end proc; plot3d(0, -1.0 .. 2.0, -2.0 .. 2.0, style = patchnogrid, orientation = [-90, 0], grid = [250, 250], scaling = constrained, color = julfn_zsqrd)

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.
