@nm In addition, the simplified representation appears to be (a bit) longer, but is easier to check:

ot := odetest(sol,ode);
ssol := simplify(evalc(sol)) assuming x>0;


@Carl Love No, that cannot be turned off, AFAIK.

@acer That feature was acutally introduced in Maple 13.02, if I recall correctly. So the OP might even benefit from it.

@Anthrazit I have deleted the attachment because it contains your Purchase Code. That is valuable information (for you) and should never be published. Please consider uploading a shortened file. Thanks.

@Lisa6 At this point, I think it's more efficient if you send your questions to our support team. Be sure to include as many details as possible: platform, purchase code, and all data you entered (target path in particular), error message. You can also include a link to this discussion thread. MaplePrimes itself is not primarily a support channel for these basic issues.

@Lisa6 Which target path did you supply when installing? Is it really empty?

The command to launch Maple from Linux command line is "xmaple" (or "maple" for the command-line version), not "Maple". Please see our installation instructions, particularly section "How to start Maple".

@Lisa6 If activating hangs under Linux, please check out our FAQ at Then try again. (Typically, you don't need to reinstall, but just run the activation tool again.) If that still fails, we can help with a so-called offline activation (which is described in our FAQs as well).

I cannot help with the 3rd party package on GitHub, sorry.

@Jonas F If you want to restrict the search space, and you are interested in numerical solutions only, run fsolve with an interval like this:


It will avoid some of the complications introduced by solve (which is the more general command).

@Jonas F Not in the sense that you can specify a certain version (or year), but for this particular equation, you can come close to the desired result by restricting to the real domain:



Can you load mw files via the File > Open menu item (or the equivalent button) in Maple 2020

[Edit: please ignore my question - I had overlooked your statement that it works.]

That is at least confirmed for the cases with int’l characters.

Please also consider tomleslie‘s suggestion.

@acer Very nice work! I did a quick test with Maple 2019.2 on 64-bit Windows 10. For the Windows platform, we just need to replace "" by "mkl_rt" in both locations. The "lib" prefix is not being used here, and the .DLL extension will be appended automagically. So I guess we can also omit the .so extension on Linux, but I would have to cross-check on my Linux box later.

Update: omitting .so will not suffice, but just specifying "mkl_rt" does work on Linux, too.

Another workaround is to simplify (or to combine) I0 before calling limit.

@Carl Love Sure. I was inspired by Kitonum's initial answer, so I just tried that way.

@Kitonum While I'm not a developer, I can say that


reveals that the result is found by a rather advanced satisfiability checker, implemented in SMTLIB. That external library was added in Maple 2017, and its coverage was expanded since.

Do not use screenshots for such questions. It makes no sense to type in anything from a screenshot. Instead, use the green arrow of the message editor, please. You can uploads mw and mws files, besides some other formats. Thank you.
