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

This doc is just an example for uploading with my post.

The above doc/worksheet can be clicked and viewed.

Youtube URL is given below. This also can be clicked and viewed. Thanks to Carl Love's suggestion, I modified using the chain link in the editor.

Hello Ladies and Gents :-)

Can someone give me the link of my previous (silly) question?

I would like to reply to Carl (Love) but I can't find the link.

Thank you.

 

Hi,
I see more and more contributions where the content of the mw file is replaced by a code snippet and, possibly, an image as illustration.
Do we have to consider this as the new norm to post question and to submit replies or answers?

(this question is related to the one Carl Love posted a few days ago  Why can't I display any worksheet? and which, if I'm not mistaken, has not been definively answered)

Not that I can't sleep quietly without it, but why is the possibility of receiving a vote or being selected as the best answer (ok, this rarely happens) no longer proposed in my replies?
For instance, in a recent reply (not the one I'm the prouder of) the header appears like this, witho ot thum nor star below "1 hour ago")


TIA

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.

It would be useful if there was a category (or subcategory) of scientific domain (e.g. physics, methematics, economics...)  in which Maple is applied. Thus it would become very convinient for someone who have a question on a specific topic to find a possible answer. 

I like how the Julia community has been organised in https://discourse.julialang.org, so I would suggest to implement something similar in Maple Primes

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.

I made a mistake in entering this expression:  2020 should have been 2018.

int(1/(x-1)+sum((k+1)*x^k,k=0..2020)/sum(x^k,k=0..2019),x);

realloc(): invalid old size

Nothing I can do from the keyboard should cause a core dump.

Hello admins. Can you please guide me on what's going wrong with my post? I just posted and now my post has been deleted or vanished?

Tried several things to get a neat grey box with Maple text in it 
What to do for making this ? 

 

 

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.

Why my quesiton I posted few hrs ago got deleted and who deleted it?

What kind of forum is this?  These things never happen at stackexchange. Here is screen shot of the question. This is not the first time this happens. I posted before questions, and they get deleted. 

 

 

I have recently taken some questions about MaplePrimes reputation scores, and coincidentally, there was a discussion about it within MaplePrimes yesterday. I wanted to address these issues, and thought that doing so as a separate post made sense.

Reputation was added back in 2010 as a mechanism to track how fellow users value your contributions, and I believe it has largely worked. It's become a great way to acknowledge the time and effort our members put into the community, and I know that many of you greatly value the scores that you have earned. I also know that it is never fun to see it drop, even by just a few points.

To be clear, there are only two ways to lose reputation:

  • If someone upvoted your answer/reply and then later rescinded the upvote
  • If someone marked your answer as the "best" answer, and then later changed their vote to another answer

This means you can only lose reputation points if someone undoes an action that gave you points in the first place. This is going to happen occasionally. For example, the user may have voted your answer “best”, but as the discussion continued, someone else posted a different solution that the user felt was even better. So you can expect to see small fluctuations from day to day, but the overall trend will be upward. 

That said, members get understandably concerned when their reputation drops, and want to know why. We have always been able to track when reputation changed, but “why it changed” was obscured. Starting today, we have added enhanced logging for reputation shifts. This will allow us to better diagnose the causes when a member is concerned about a change to their reputation points. As well, in the very unlikely event that there is malicious behavior on MaplePrimes, this will give also us the data we need to take action to protect the community.
