MaplePrimes Questions

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.

For constants I prefer subscripts over indeces.

I noticed that numbers in subscripts are printed in italic. This is against a common prettyprint convention, where variables are in italic and numbers are in roman. In the example below "1" can easily be misread as "l" (which is probably one of the reasons for this convention)

Is there a way to get numbers printed in roman in subscripts? To force roman print I tried

t__`#mo("1");`
Error, missing operator or `;`

In 2d-Math the convention is respected in the input but not in the outut

ut + 1/2(u^2)x −uxx =0, u(x,0)=x.

my answer is so different but  and i want remove this lambert in my test? can we do something for giving question exactly solve the question by model i have a book of ode which a lot of time i do some trail but have a problem? how i can remove this issue specially for bernoli and  other type?

restart

with(DEtools, odeadvisor)

ode := diff(y(x), x)+x/y(x)+2 = 0

diff(y(x), x)+x/y(x)+2 = 0

I want both Pc and r(Pc) to be greater than or equal to zero. The only constraint is that all parameters for which I’ve provided data must remain positive. Can we identify the key parameters that significantly affect Pc? Also, what condition ensures that Pc ≥ 0? Ideally, I’d like Pc to be less than or equal to Pu. Could you suggest what changes in the numerical values I should make to ensure Pc becomes a positive value?

Attaching file: Q2.mw

Can we include a graph that shows how Pc changes with respect to variations in the most sensitive parameters?

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)

With the new Maple-2025 the GUI-fonts are tiny and more or less not readable on a 5K Monitor. The old solution using this options here:

JVM_OPTIONS="-Dsun.java2d.pmoffscreen=false -Djogamp.gluegen.UseTempJarCache=false -Dswing.plaf.metal.userFont=\"Tahoma-36\" -Dswing.plaf.metal.controlFont=\"Tahoma-36\" "

does not change the GUI fonts, as it has worked up to Maple 2024. 

Is there a single-source fractional calculus toolbox, or collection of tools, available for Maple ? There appears to be the odd routine for fractional derivatives or DE's, but nothing of a systemic nature.
