Not able to make odetest give zero on this Maple solution to this first order ode.

So not sure if solution is correct or not, as can't also get same solution by hand.

Any one can find a method or way to verify this solution is correct?

odetest says it satisfies the IC but not the ode itself.

Below is worksheet. Tried with Maple 2026 and 2025.2 both give same solution.

Site will not let me upload worksheet. Here is code

ode:=diff(diff(y(x),x),x)+sin(y(x)) = 0;
IC:=y(infinity) = Pi;
sol:=[dsolve([ode,IC])];

the_residue:=odetest(sol[1],[ode,IC]);
the_residue:=odetest(sol[2],[ode,IC]);

Tried many things, including different assumptions, but can't get zero.

There seems to be a regression in Maple 2026 in the XMLTools:-ParseFile function.

As Maple2026 is not yet in the list of products to be chosen, I have added it in the subject.

Error, (in XMLTools:-ParseFile) invalid input: too many and/or wrong type of arguments passed to XMLTools:-NSXML:-Parser:-ParseFile; first unused argument is prolog = true

The test file is right from the help related to ParseFile.

On Windows 11.

When I insert a link to a worksheet Maple 2025 crashes (also with the Screen Reader version).

When I click on a hyperlink to a workbook in a document created with Maple 2024, Maple 2025 crashes.

Is this reproducible?

Edit:

Also opening a workbook crashes Maple 2025 (i.e. no hyperlinks involved)

[update: Maple 2026]

I have tried to reinstall the redistributable

but get error messages

(Should I install x86 instead?)

Could it be that the installation (of Maple and the redistributable) only works when logged in as an administrator instead of installing an update as administrator (beeing logged-in as standard user)?

Can someone confirm that inserting a hyperlink crashes Maple 2026 on Windows (11)?

Has anybody a workaround to link to a locally saved worksheet?
