Why does Maple 2022 still have only a history of ten files in the Recents ?

It makes it very difficult to search for files you opened but only realised later you need, but then it is long out of the silly 10 history list.

Isnt there a way to make a perpetual list so that all files opened are saved chronologiacally against date, or... at least be able to increase the silly 10 recent files to something like 30

Thanks

I have Maple 2022 open with a worksheet on a specific workspace.

I then move to a different workspace and want to start a new instance of maple for a new problem.

In command line I exacute

$]xmaple22 –standalone  filename.mw

Unfortunately when the new instance is started, the open maple instance on the first workspace is moved automatically to the second workspace together with the new instance opened, completely messing up the organization.

This is not expected behavior.

How can I make Maple execute absolutely independent instances of xmaple22 without indiscressionately and automatically moving existing open maple instances to the current workspace.

Severely annoying. Maple 9.5 e.g. does not have this behavior at all so Maple 2022 is a step backwards in this regard.

Thanks

I fail to understand from the manual how to do total differentiation.

e.g let's say I have a trivial transform defined as

u=t(x,y)-s(x,y);

then I should get

du=diff(t,x)dx+diff(t,y)dy ...etc

Apparently the operator D_Dx should be able to perform the total derivative, but somehow I cant see this is possible.

What do I miss ?

Through the years I basically had to work with the fact that Maple prefers to express results in terms on Cos^2(x) and not Sin^2(x).

With older Maple versions there was never a workaround by means of a command that would convert an expression in terms of sin^2(x) if Maple expressed it as cos^2x.

Is there any way in the newer Maple versions to convert output to be expressed rather as sin(x).

It becomes a bit old, to always substitute the identitity manually to convert.

Any easy way  for this in new versions.

If I set up

DGsetup([t, r, theta, phi, psi], M1, verbose)

then the frame-name M1 is displayed with every new execution group prompt as "M1 >"

How do I switch off the frame-name to be displayed at the prompt, so I only get ">" ?

It is irritating as heck !

The only way around this is to restart the kernel, then I can add new execution groups without frame-names displayed.

Thanks
