I’m working on deriving the equation of motion (16) from equation (9) (see attached image), but I’ve encountered a couple of issues in Maple. i) The variational derivative of Lagrangian, and ii) the commutator is zero, which isn’t expected.

How do we fix these issues? Are there any specific packages regarding the construction of Lagrangian?

I can't understand why Maple interprets 1 .05  as 1 * 5 = 5 , and 2 .05  as 2 * 5 = 10 . Note the space between 1 and .05
In a different calculation I accidentally inserted a space between 1 and .05, and received a strange answer, and finally narrowed it down to a space.
But now I wonder why it is it is interpreting this way. Also I see that 2  0.05 produces an error. But  2 .05 is treated as 10. There is an implied multiplication? But the multiplication should be 2 * .05 , which is 1 and not 10.

I have encountered an issue: eq1 is not satisfied, though eq2 is satisfied for the parametric value (10). I need assistance in finding a way to ensure that both equations are satisfied simultaneously. Please provide guidance or suggest a potential approach for addressing this issue.verf_kk.mw

How can I substitute equation (5) into equation (4) to obtain the final form [see image in BE.mw]?

Additionally, how can I use subscript notation for derivatives, such as expressing  as ​?

By using the 'declare' command in Maple, one can utilize subscript notation. However, in this case, the function must be written in terms of τ and σ on each step.

Could anyone help me to convert a code written in Mathematica to a Maple worksheet? I have PDF only. Could any one have a look on Mpale sheet and PDF....

Hi,

I recently moved from Windows 10 to Windows 11. I am using Maple 2022.2, and I got that installed and working OK. 

I have four Maple worksheets that I have saved as tasks on Windows 10, but my OS move requires some adjustments. When I try save the modified worksheets to the default Maple help database, I get an error saying that the database is read-only. When I try to make a new database file, Maple asks if it should create it, but then I get an error that Maple can't open the new database.

Suggestions?

Thanks,

Jno.

I have some lecture notes and examples that suddenly appears to be corrupted. I am getting the following error code when trying to open the file: "There was a problem in the loading process, you worksheet may be incomplete."

I've tried the following trouvleshooting:

- Close and reopen Maple

- Restarting computer

- Tried different computer

note: I have no backup files as I do not have autosave switched on.

I have also tried looking into the solution posted on a previous question on this site (https://www.mapleprimes.com/questions/235363-How-To-Fix-Corrupted-Maple-File), i.e.  changing the file format to.xml and making changes but with no luck :(

Is anyone able to help me fix it and un-corrupt this file:
