Good day everyone, please I'm soliciting help on how to solve PDE in Maple. I know how to solve ODE but I don't know how to go about PDE. The problem I want to solve is attached as an attachment. If epsilon is zero, then the problem reduces to ODE which can easily be solved, but epsilon is not supposed to be zero. please I need your help, thank you in anticipation.

I'd like to delete my mapleprime account and purge all associated data. How to achieve this?

I started using maple around 1995 on the Inverse Symbolic Calculator to discover the MRB constant and got put on this list.

Do you consider yourself to be one?

The last several times that I've tried to use the Delete As Spam feature I've gotten an error message Error Generating Page, and the spam was not deleted. Anyone know what's happening? 

In an answer to an earlier question

https://mapleprimes.com/questions/232067-Error-Invalid-Neutral-Operator

I inadvertently used the "Insert Contents" link - AND IT WORKED

Anybody know how long this has been fixed?

Would be nice if someone could add Maple 2021 to Software Change Requests list.

Right now Maple 2021 is unusable for us due to a big problem related to saving workbooks.

Dear administration, I hope you all are good,why my question have been deleted? My question is a little similar to the one before, but there are still a lot of differences.I didn't do a backup which was bad.Once deleted, there is no chance of modification.

Two days ago I have answered a question about using numapprox:-infnorm for functions of several variables. The question is now deleted. Is it possible to find whether it was deleted by the author (even if she/he has used the "best answer" tag)?

Dear administration, I hope you all are good, why my question have been deleted? Even my important question on legends was deleted.

Dear all

I have  Lie commutations for vectors e1, e2, e3, e4, e5, e6 as follow:

[e1, e3] = e3, [e1, e4] = e4, [e1, e5] = e5, [e1, e6] = e6, [e2, e3] = -e5, [e2, e4] = e6, [e3, e5] = e6

for which the command 

Query("Jacobi")

returns the false result, which means, the vectors are not closed under Jacobi's identity. How can I find vector triplets for which Jacobi's identity does not hold?

Please find Maple file.Jacobi_identity.mw

It's been about a year since I've been able to display any worksheet at all on MaplePrimes. In the example below, I took a very simple worksheet that had been displayed in an Answer to another recent Question and tried to upload it. So, we know that it's somehow possible to display this particular worksheet on MaplePrimes.

When I select "oldest first", the first post shown is the newest.  Vice-versa when selecting "newest first".  Am I misunderstanding the meaning of the term?  I suppose it doesn't matter as both options are available but it's weird.

How can I find the corresponding group for the Lie algebra given in the picture (using Maplesoft software)?

Also, the command Lies Third Theorem works only for Solvable representations. What to for unsolvable representation.

Not that I care about the virtual rating numbers here, but I am wondering why would one suddenly lose 15 point after posting a problem they found in Maple? Is this typical?

3 hrs ago, I was 3001  and when I came to check on the status if any, now it says 2986.

Just wondering why, that is all. Again, this really does not bother me at all as I do not care about these virtual cloud credit points, and I only post here on occasions and when I found some problem. I just like to know why this happened just now, that is all. 

I had difficulty in making my latest post.  It would fail at Submit.

I had success when I saved a draft post.  I was able to edit the draft to submit.
