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. 

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.

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.

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.

As I was numerically investigating this recent question I incidentally discovered a strange behaviour of Maple 2015 (which maybe exists in more recent versions?)

The attached worksheet presents an erratic behaviour (plus a remanance isssue because saving it, and opening it again changes the displays).
Note that this strange behaviour seems to occur only when tickmarks use the atomic name `#mo("2")`.

Here is a pdf print of this same worksheet: as I hope you will see (because I don't know what you are about to see when opening the attached worksheet) its content differs from the worksheet's.

Here are 3 screen captures which show what MY worksheet looks like

There is a typo in the comment below: read "void" instead of "coid", sorry for the mistake.

Is this a Maple 2015 issue which has been fixed in earlier versions?
Is there a way to fix these issues?

The attached file "test" asks for the largest power of two contained as a factor in a term. This is easily solved using "simplify." How can this be achieved using factorization?

I'm updating to Maple 2025. Are there any feature differences between Linux and Windows versions?

Thanks.

Thanks for the help with the recursion problem, here's a very challenging problem for the weekend ;-). It should be solvable in Maple, at least for examples. I only know of one very theoretical, unfinished solution that I'm still working on:
Given a closed convex curve in the Euclidean plane. It is multiply continuously differentiable, and the curvature is also continuous.
Then there are at least three pairs of points on the curve with the following property:
The tangents at the points of each pair are parallel to each other, and the curvatures are equal.

A lot of time i finded but i have a dubt about this why this is happen each time number of equation for finding parameter a_12 is 4 but this time is 28 which i thoght some thing must be mistake also the author of paper use  u=2(ln(f))_xx which is wronge and not satisfy but i try to find R which is strange again is not number contain parameter but is satisfy also in equation 14 i don't know each i is 2 or 1 or it can be i remain itself?

thanks for any help ?

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.

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.

According to the attached file "test" I would like to determine the limit of the function f(n,x) for n-->00 as an exercise. I'm asking for advice on using "rsolve". I also want to calculate the limit of sqrt((n/3))*f(n,x) for n-->00 using f(n,x) from the file "test". I also need help with this. (This isn't a school assignment ;-).)

I encountered this bizarre inconsistency issue that Maple18 generates different outputs when executing the same command:

test_res2:= factor( simplify( expand( value( subs( Perturbation_Sol, EQ_PX2_order_7 ) ) ) ) )

'EQ_PX2_order_7' is a rational expression in sin(i0), cos(i0), sin(uL), and cos(uL) with rational coefficient terms. It also has inert differentiation terms Diff( * , uL ).

'Perturbation_Sol' is a set of 171 elements in the form of 'parameter_name = expression'.

My goal is to check if substituting 'Perturbation_Sol' into 'EQ_PX2_order_7' yields 0. Since 'EQ_PX2_order_7' has inert differentiation terms, I've applied 'value' after using 'subs'. Then I apply 'expand', 'simplify', and 'factor' to reduce the result to the simplest form.

However, Maple18 generates different outputs when I just execute this repeatedly. Please see the worksheet "test.mw" for details. Any insight will be greatly appreciated! Also, I wonder if the same issue would happen when the worksheet is executed with newer versions of Maple.

Only for my understanding:
Why is the concatenation operator not working in this assignment on the righthand side

for i to 5 do
  x_ || i := x_ ||(i-1); 
end do;
                           x_1 := x_0

                           x_2 := x_0

                           x_3 := x_0

                           x_4 := x_0

                           x_5 := x_0

Somehow i in (i-1) equals always 1
Why do I have to use

for i to 5 do      
  x_ || i := cat(x_,i-1);  
end do;  
                           x_1 := x_0

                           x_2 := x_1

                           x_3 := x_2

                           x_4 := x_3

                           x_5 := x_4
