I am on Linux using Maple 2025. When I did

PackageTools:-Install(5137472255164416);

It gives error 

Is this expected? I thought to check before trying again with the overwrite=true. Is the above because I have Physics update installed?

Physics:-Version()

The "Physics Updates" version in the MapleCloud is 1861 and is 

   the same as the version installed in this computer, created 

   2025, April 10, 15:58 hours Pacific Time.

If this error is expected first time, you might want to mention this in your post also so others are aware they can see it.

Update:

I did PackageTools:-Install(5137472255164416,overwrite=true); then closed all of Maple and restarted it, but when I type SupportTools:-Version() in new worksheet, it says

                 Error, `SupportTools` does not evaluate to a module

And ?SupportTools does not bring up anything.

Does this mean it was not installed? I am using Maple 2025 on Linux. 

Should I try the command PackageTools:-Install(5137472255164416,overwrite=true); again?

update

I tried the command above again, but it keeps saying Error, `SupportTools` does not evaluate to a module
Here is worksheet

ps. I just noticed the number you show to use, is same as PhysicsUpdates number given in this post The-2025-Maplesoft-Physics-Updates-And-Its-Future

But this installs the Physics Updates, which I already have installed in Maple 2025.  So I am confused now. Why then does your post say

"In Maple 2025.0, the SupportTools package is not installed by default. For the first installation, you can also run the command
PackageTools:-Install(5137472255164416); instead of installing it from the Maple Cloud."

While the post about Physics update says

"On that note, the first release of the Physics Updates for Maple 2025—focused solely on the Physics package—went out today as version 1854. To install it, the first time open Maple 2025 and use the Maplecloud toolbar -> Packages, or else input PackageTools:-Install(5137472255164416). "

Is SupportTools same as PhysicsUpdate now?

fyi, what is symplify  command? There is no such command in Maple 2025. I assume these are all typos in your plain text input and you meant to write simplify.

what should the result of simplification be? (just to be clear). This is what another software gives

Is this what you are expecting from Maple also?

@Alfred_F 

Thanks.  Could you share the other initial condition that gave solution? I'd like to add that also to my test suite for Abel ode's.

@aroche 

Thanks for looking into it. You must be using internal development version, as Maple 2025 only finds the first solution y=x^(2/3) using Lie symmetry.

Fyi, the division by zero also shows up using Chini. I noticed looking at the trace, when asking for only the general solution, Maple used Chini and not Abel.

But then when asking it to explicitly use Chini with the IC now added, it also gives divison by zero also. Looks like same issue.

I prefer Maple to concentrate only on symbolics. That is what it is best at. For numerics, there are many others and also better options.  

But Maple seems these days to want to be the jack of all trades and master of none.

By trying to chase all that is fashionable today, It will end up losing market share in all areas.

There are still many things Maple does not do in symbolics or can do better. Also its debugger is hard to use and have not been updated for decades.

I can make a list of 100 things Maple can do better in symbolics or missing features in symbolics. One quick one is symbolic series solution to ode using asymptotic expansion when expansion point is irregular singular point.

No need to waste time on numerical solvers which no one will use because other software is better at it.

It is much much harder to be good at symbolic computation than numerics. That is why there are really only two major CAS software out there. For numerical software, there are 100's.

So concentrate on what you are good at and make it better.

Ok, enough rambling. 

I have not seen this myself. I use worksheet and not document mode. And use Maple 1D for input. Do not know if this makes difference.

But this is definitly looks like some kind of java swing unicode characters rendering issue. The Maple front end uses Java. May be 2D math for input makes it show more also.

I spend 90% of my time using notepad++ to write Maple code, in plain text .mpl files, and use worksheets just to run tests and try things and for using the debugger, so may be this is why I did not see this.

It is good idea to report it to Maplesoft even though you can not make example to reproduce it.

@Alfred_F 

When I asked google AI on this, it said

"No, a Frobenius series does not necessarily have to converge uniformly. While Frobenius series can converge pointwise, they may not converge uniformly in all cases."

But without using the limit, how else will one find the constants of integration? Are you saying the series must be assumed to have  uniform convergence to use the limit as above?  Can't just plugin in x=0, as that gives division by zero.

I assume Maple also used the limit internally to solve for C2 in this example and give the answer it did. How else could it have found the solution it did otherwise? 

@Alfred_F 

This is how I solved it, which I assume same how Maple does it internally. The solution with no IC is 

ode:=x*diff(y(x),x$2)+y(x)=0;
Order:=4;
sol_with_no_IC:=dsolve(ode,y(x),'series');

Lets write the above as   y=c1*y1 + c2*y2

At x=0 the above becomes

          1 = c1*limit(y1,x=0) + c2* limit(y2,x=0)

Asking Maple for limits above, it says limit(y1,x=0)=0 and  limit(y2,x=0)=1. Hence we have

          1 = c2

general series solution now becomes

            y=c1*y1 + y2

And this is what Maple gives.

@Alfred_F 

Maple's solution is correct. I solved this by hand and get same exact solution as Maple using same IC ofcourse.

The problem is not that the solution being correct or not. It is why odetest fail to verify it.

Since Maple generated this solution, it seems strange that Maple is saying it is unable to compute series to verify the solution !  

@Kitonum 

I tried both before and Maple can't solve either of them due to nonlinearity. I do not think you used the exact pde given by user. I read it as 1/2*x*u(x,t)^2 for second term and not  1/2*diff(u(x,t),x)^2. At least this is how I read 1/2(u^2)x as.

Ofcourse I could be wrong and they meant this to be 1/2*diff(u(x,t),x)^2 as you did, but this would be very strange way to say this, because they could have used  (ux)^2 as they did for first term ut to mean diff(u(x,t),t).

Maple forum should really support Latex input and rendering one day. This will make reading math equations more clear.  This assumes people know Latex, but every one these days who does any thing related to math must know latex :)

@MichalKvasnicka 

Do you have exact URL you used to obtain the above page? Inside Maple itself, it shows 2025 when clicking on the icon "what is new" it gives

And on the web, using this URL https://www.maplesoft.com/products/maple/new_features/  it gives 2025 also:

Is it possible you used different URL that went to old help page? Also you can try clearing the cache from your browser just in case.

Update

I found how you got there. You are right. Here are the steps to reproduce it

1. Click on https://www.maplesoft.com/support/help/

2. On the left, expand the "what's new and release notes" by clicking on the "+"

3. Click on the item that says "overview"  

And it does show Maple 2023. We see the link that overview points to is

  https://www.maplesoft.com/support/help/Maple/view.aspx?path=updates/v2023&cid=37

Which should be   updates/v2025  instead of updates/v2023

It looks like someone needs to get some links updated there.

@Carl Love 

Thanks, I got a chance to test your code. But unfortunately, when I use LibDir.mpl, I see very random behavior by Maple. sometimes odetest times out, sometimes it gives zero very quickly, and sometimes it given non-zero large expression. All using same exact input

Here is worksheet. This is using Maple 2025 on Linux.

Download no_remember_april_5_2025.mw

And when I removed your library, now Maple gave the long output each time (no timeout and no zero output). So it seems removing the remember tables leads to more unpredictable behaviour by Maple.

@phil2 

Thanks! YES!! It works when using maple script under bin

I had no idea that there is a maple script under bin for Linux. I thought one should use cmaple just like I do on windows when I want to run the Maple command line.

Is bin/maple then what one should use instead of bin.X86_64_LINUX/cmaple , and they do have the same API as described in 

If so, why are they both there?

May be for future version, bin/maple can replace bin.X86_64_LINUX/cmaple to reduce confusion for users on Linux, since one seems to work but not the other.

Thanks, I have to test this more but for the above it works now.

@TechnicalSupport 

Thanks for the links. Yes, this definitely looks like screen tearing. But it only shows when using Maple on windows 10 for me, and with no other windows 10 apps.

I have latest NVidia driver for the graphics card I am using and always select clean installation. I just updated it also now:

However, this changes nothing. I just tried it again. the UI does screen tearing each time:

I am trying Maple 2025 now on Linux, on same PC running in Virtual box. I have 13 days left on my trial. So far, the UI there is working with no issues at all. No screen tearing. So I am trying it there and if it works ok after more testing, I will switch to Linux and buy new PC and use Maple there.

I have this sceen tearing with Maple 2204.2 also, but not as bad as with Maple 2025. Here is a link

Using same PC. windows 10 PRO.
