Mapleprimes advanced search isn't working properly

Mapleprimes - please fix

Hello 
I have two questions if you please.
Q1)
Is there any kind of a ruler in the maple worksheet that helps me to Adjust the wideness of the line text? 0r even to  spilt the outputs in two columns 
you know as the ruler in the "Word document ".
Q2) Is there any way"method" to change the output type 
since the default adjustment of the outputs is a type of stretchable image? But I need the outputs of the text type. That may  help me to insert them in a given templet

Thank you

How can we manage them?

During the last few days
@Rana47 https://www.mapleprimes.com/questions/236758-HPM-Error-Invalid-Input
@SHIVAS https://www.mapleprimes.com/questions/236755-How-To-Run-Or-Implement-HPM-Method-In-Maple
@Madhukesh J K https://www.mapleprimes.com/questions/236747-Error-In-The-Program-HPM

have both asked a similar question on the same topic (HPM) and uploaded both quite the same code (same name of variables, same commands and same syntax errors).
This reveals an obvious close proximity of these three OP.

Given the extreme resemblance of the three threads, my guess is that there is a single person behind those three login names who expects that asking the same question from different login names will prevent the moderators from moving the new thread to an old one, and thus keeping his question in the foreground?

Am I on the wrong track (in which case I humbly ask the three OPs to excuse my words^[1])
If not, how can we prevent this type of behaviour?

^[1] but, as it is likely that they are then close colleagues from the same lab they should coordinate not to ask the same question three times.

Earlier today I observed this:



What would be the reason?

What do you think is the acceptable limit to the effort required to answer a question?

At what point does the question-and-answer game between two contributors become unreasonable?

How do you, the most highly ranked, deal with situations that last for days?

In the following I show two functions f and g where ShowSolution(Limit(..)) works for f but not for g. Any idea why?

with(Student[Calculus1]);

f := x^2 + x:
limit(f, x = -infinity);
infinity
ShowSolution(Limit(f, x = -infinity), maxsteps = 100);
// step-by-step solution is produced

g := x^2 + 3*x:
limit(g, x = -infinity);
infinity
ShowSolution(Limit(g, x = -infinity), maxsteps = 100);
Error, (in Student:-Calculus1:-ShowSolution) unable to compute solution steps

Maple is able to change f into an equivalent expression by factoring out x^2, but does not seem to be able to do it with g.

I attach two screenshots that show this curious behaviour.

Often, in response to a question without code, the suggestion is made to upload a Maple file using the button with the green arrow .

This happens so often that I get the impression that new users don't recognize this as the best and most efficient way to get their question analyzed and answered. Or they just don't know how to do it.

So why not adding a hint to consider uploading code just before "Suggested Tags"?

Hey everyone,

I've been experiencing some issues with Mapleprimes on my laptop. Whenever I try to access the website, it takes an unusually long time to load, and sometimes it doesn't even load at all. This is quite frustrating as I need to use Mapleprimes for my research work. I've tried accessing the website on other devices, and it works fine, so I'm confident that the issue is with my laptop. Has anyone else experienced this problem? Any suggestions on how to fix it?

Thanks in advance for your help!

I have posted a question in the last couple of days:

https://www.mapleprimes.com/questions/235958-How-Do-I-Get-Of-HIGHLIGHT-And-MARK-Annotations?sq=235958

which was taken down by this member:

https://www.mapleprimes.com/users/acer/reputation

where (s)he posted in a previous question of mine, that the new question is a duplicate.

https://www.mapleprimes.com/questions/235909-Latex-In-ShowSolution

You cannot find his/her reply where (s(he states that the question is a duplicate.

I have replied to his/her reply and explained that my new question is not a duplicate.

(S)he deleted his initial reply together with my reply, and substituted it with what you can see on the page now:

Please stop posting completely separate new Question threads on this issue.

This person wrongly declared that my question is a duplicate, and did not even bother to take into account my reply. (S)he can delete whatever (s)he wants, and just barks orders.

Now, is this really normal support behaviour? Why is this person shutting my questions down? Is this the kind of support a person gets for paying for an expensive software?

Where do I escalate this issue?

Yesterday (?) there was a nice question which was answered by VV using Jensen's inequality.

Where is it now?

For the attached worksheet "insert contents" worked two month ago. My computer settings have not changed since.

The same happens with an empty worksheet (document mode) created with 2022.2

Maple Worksheet - Error

There is a button at the top right corner that has an icon that seems to say 4pi/3. When I hover over it is says "Maple Math". I click on it, and insert an expression that I copy directly from Maple: a simple definition of a function. There is an error that says "You have entered an invalid Maple expression". Why? The function is defined as z__1 := (x,y) -> x+y. Perhaps the issue is the subscript. I don't know but the UI does not tell me.

Here is an example that does not give an error in the form when I click the aforementioned "Maple Math" button. However, what I see below is a broken icon and the equation f := (x,y) -> x + y (exactly like this).

I am bewildered by the brokenness of this UI. 

Not the first time that a question (OP's name  PhearunSeng ) is removed as I am writing an answer (I guess other people have already faced the same inconvenience). 
Why doesn't exist a mechanism which prevents removing, deleting, displacing a question where someone (here Carl) has akready given an answer ???

Whatever the reason, here is my answer

Title: Can be done quickly if you write the matrix in a more abstract form

MyKGff := Matrix(5, 5, 
  {
    (1, 1) = A+(1/63368)*B, 
    (1, 2) = -(1/63368)*B, 
    (1, 3) = -(1/39605)*B, 
    (1, 4) = 0, 
    (1, 5) = 0, 
    (2, 1) = -(1/63368)*B, 
    (2, 2) = (1/63368)*B+C, 
    (2, 3) = (1/39605)*B, 
    (2, 4) = -C, 
    (2, 5) = 0, 
    (3, 1) = -(1/39605)*B, 
    (3, 2) = (1/39605)*B, 
    (3, 3) = (8/198025)*B, 
    (3, 4) = 0, 
    (3, 5) = 0, 
    (4, 1) = 0, 
    (4, 2) = -C, 
    (4, 3) = 0, 
    (4, 4) = C+(1/63368)*F, 
    (4, 5) = -(1/39605)*F, 
    (5, 1) = 0, 
    (5, 2) = 0, 
    (5, 3) = 0, 
    (5, 4) = -(1/39605)*F, 
    (5, 5) = (8/198025)*F
  }
);

Then (Maple 2015.2)

PseudoInverse := CodeTools:-Usage( LinearAlgebra:-MatrixInverse(MyKGff, method=pseudo) ):
memory used=28.38MiB, alloc change=68.00MiB, cpu time=312.00ms, real time=314.00ms, gc time=24.90ms

To recover the pseudo inverse with original data do

Rewrite := [
             A = (D__pile*W[1] . E__c)/3000, 
             B = (D__pile*W[2] . E__c)*89^(1/2), 
             C = (D__pile*W[3] . E__c)/1000, 
             F = (D__pile*W[4] . E__c)*89^(1/2)
           ]:

eval(PseudoInverse, Rewrite):

@ASHAN's question was about a linestyle which wasn't displayed as expected.

Maybe a handling error on my part?

There is something wrong with the search in mapleprimes. 

I noted one users comment last week about using the search to find something being very difficult to find.  The results don't often match the search.  Only just this morning I was looking for something and the results were less than satisfying often pointing to a list of more results which didn't seem to help. 

This has been a problem for a long time, is this going to be looked at or fixed soon?
