As a newbie in Maple2024, my next step is to try to solve a Diophantine equation. Attempts with isolve failed. It is the famous task B3 from the IMO of 1988:

If for integers x and y the fraction (x^2+y^2)/(1+x*y) is a positive integer, then it is actually a square number.

The solution is well known. But I would like to learn how to use Maple using this example and would like some advice.

So I have this Maple document that I worked on yesterday, and now when I open it it just opens as the start-up screen where I can choose between document and worksheet mode. I can see that the file is much larger (900 kb) than an empty document, so it should definitely have the data still in there, but opening it with a text editor I couldn't manage to fix my issue. Does anyone have any tips? I have a back-up of the file (from the restore backup menu), but most of the content is not there, so it would be very helpful to get this one fixed.

By using the second order ODE and its solution how i can get thus changing Rule?  i am looking for equation (8) by assumption of the paper he did, there is a trick but i don't know

Dear Power Users, Dataframes are a powerful tool within Maple. However, when I have 'undefined' in cells "Aggregate" or "DataSummary" does not provide answers. However, when I use "Statistics:-Mean" with the additional option "ignore=true" I can get an answer for one column (see attached worksheet). Adding "ignore" to aggregate apparently does not work. What is the method for ignoring the undefined data? In Excel when a cell is blank it will be ignored. Thank you for any help given.MP_Aggregate.mw

Ive been wondering what i can use this for and where maybe it has been overlooked ,if any one has any ideas im really interested, that pi^ cubed

I analyzed the kinetic equation of the system and got this formula. I want to realize the sweep frequency analysis of the kinetic function by changing the size of omega2, but I don't know how to write a program. Want to ask for help

In the Standard interface, the length of an expression that display in the worksheet can be limited using the Options dialog: Options Dialog - Precision Tab - Maple Help. However, I would like to know if I can change this option programmatically. The closest interface variables are elisiontermsbefore, elisiontermsafter and termelisionthreshold, but as the aforementioned help page states, they control the “term elision” and are not the same as “expression length limit”. So, is this possible? 

Maple help pages keep getting worst with each release.

I want all input to be displayed using Maple 1D notation, so I can copy the example to my worksheet since I only use worksheet and not document (2D) mode.

So even though the first thing I do when I open help it to turn off the 

                     view->Display examples with 2D

So it is no longer checked, I still see many pages using 2D math for input. 

Here is one example ?D  page

If I copy one such input to my worksheet now it looks like this

eveything in 2D becomes ?? when I copy it.

So one can only look but not copy?

Is there any other option to make sure, really make sure, all examples have 1D as input?

The problem is that it is all not consistent. Some examples have a mix of 2D and 1D as the above page. Some are in 2D and some are in 1D.

And this is all on the same help page!

Does no one inside Maplesoft even look at their own help pages?
 

In calculation limit, signum and infinity appear!!!

Is this correct?

Dear all
I have an equation, I would like to dermine the exact solution, but maple return an error

Thank you

I am trying to understand under which conditions submenus disappear.

Now I have seen that the context panel is empty when submenues disappear.

Has anybody noticed the same and are there other instances when the context panel is emtpy?

Both effects could have the same rootcause.

Here is an example:
A -> no submenu

B -> Empty context panel

C -> Menu appears inside workspace (first time I see that)

Update

C seems to happen when the Maple window is not maximized to the full screen. -> then the context pannel becomes empty (for some reason) -> then if the Maple window is maximized to full screen we see C. Opeing new documents do not show this when toggling between and

Hi everyone,

I’m encountering an issue with Maple 2024 on my MacBook Air M1 (2020) running macOS Sonoma 14.6.1. Every time I try to log in to Maple Cloud from within the application, the entire program freezes and becomes unresponsive. I’ve tried restarting the application and my MacBook, but the problem persists.

Is anyone else experiencing similar issues with Maple 2024 on an M1 Mac running macOS Sonoma? If so, have you found any solutions or workarounds? I’ve checked for updates and even reinstalled the software, but the problem still exists.

Any help or advice would be greatly appreciated!

Thanks in advance!

This problem began about 3 nights ago.

When I load the subpackage UHG to RationalTrigonometry no warning.

When I rerun the worksheet warnings appear. If I put in arestart and reload the packages no warning. The problem only occurs with the sub packageUHG. The RationalTrigonometry package also has a few aliases.

Screen shot of one rerun  then added restart.

i have solution of ODE but again i want take derivative from solution function F then i want take reciprocal of derivative
if F'=G then i want 1/F'=1/G like that i want all solution by list and if possible don't give the parameter a sequence  it will be better

thanks for any help
