MaplePrimes Questions and Posts

These are Posts and Questions associated with the product, MaplePrimes

I have noticed that I don't receive e-mails anymore when contributions are submitted to my subscriptions.
I used to.
Has this happened to anyone else?

It is embarrasing to have asked somebody a question and gotten a reply you are not made aware of.

What to do about it?
 

"The account type or email address or password is incorrect."

None of those things is true. Using those same credentials, I am able to log in to Maple Cloud in my office but not from home. 

Has anyone else had this problem or know of a solution?

Thanks!

Running Maple 2017 in office on Windows 7 and at home on Windows 10.

Office copy is through a site license purchased by my university. Home copy is a personal home-use copy obtained through the Maple Adoption program.

I saw a question earlier today regarding 3 particles in a gravitational field.  It has since disappeared. 

I see no rhyme or reason why it was deleted by someone, whoever did.  It was Math related and it was Maple related hence no reason for it's deletion.  This happened just before Mapleprimes and Maplesoft went offline for a couple of hours. 

Can someone explain?  Did anyone else see it?

Searching for "typeset but do not execute" in MaplePrimes returns several hits.  The following looks primising:

Clicking on that link, however, leads to a page which has nothing to do with the searched item.  How does one navigate to the correct page?

Greetings to all.

My apologies if this is a repeat, I could not ascertain if this question has been asked before. I am not able to enter a tilde in my home page URL in my profile. I used the escape sequence %7E as a workaround. This does not work in all browsers however, e.g. the page displays correctly in Chrome but not in Firefox. How to enter the tilde into my profile URL? (The tilde is commonly used to indicate the directory public_html in a user's home directory by the Apache web server.) Thank you.

Is there a problem with MaplePrime web site?   All my questions for the last 4 years, and answers are no longer available. All gone. I posted a question early today about sin(x) calling. one hr after that, I noticed all my questions and answers gone.

When I go to my user profile, it says I have zero questions, zero answer and zero post for the last 4 years. All the answers to my questions also got deleted, which is a shame if this happened. They have many useful information.

Any one else affected by this?

Hi!

Everyone,

I want to draw  phase plane of system of three fractional order equations. 

 

Note that 

Also want the  phase portrait when the values of alpha are not same....

Also

Thanks

 

 

 

I  encountered a non-integrable integral in the process of solving the following process, . How to achieve its numerical solution? Such as in a looping   code:

#######
pa[i] := pa[i-1]-(Int(subs(t = tau, Lpa[i-1]+Na1[i-1]-Na2[i-1]), tau = 0 .. t)); 

pw[i] := pw[i-1]-(Int(subs(t = tau, Lpw[i-1]+Nw1[i-1]-Nw2[i-1]), tau = 0 .. t)); u[i] := u[i-1]-(Int(subs(t = tau, Lu[i-1]+Nu1[i-1]+Nu2[i-1]), tau = 0 .. t));

######
Detailed code see annexBC2.mw

Dear all

I have n, p two integers greater than one

I would like to minimize the following real number by a fixed positive constant if its possible

(n/(n+p))^(n/p)-(n/(n+p))^((n+p)/p)

Many thanks

Couldn't any question with title beginning with http be removed automatically? There has been quite a few containing nothing but spam.

I saw yesterday evening (at home) a very elegant answer to my question "Intersection of real intervals" .
Unfortunately I can't retrieve it this morning (I'm in the office)

It was something like  coulitbe('_x' ...) ... but I don't remember it entirely
I think it came from Carl Love or maybe Mac Dude

 Could you please send me it again ?

 

Thanks

Hello

I am a student of an engineering career

The math teacher is going to ask us to solve some exercises Matlab

The teacher is very hard and explains nothing of Matlab in class

We must learn to use the program on our own viewing internet watching tutorials

I was wondering if somebody could help solve some exercises.

Are only three exercises which are imposible to me

I would appreciate it greatly.

Thank you

For the last 24hrs or so I have found it almost impossible to upload worksheet files in response to questions.

My usual approach is

Big green up-arrow:
(uploader pop-up appears)

Browse files

(this still works)

Upload file

This is the problem step - I generally just get "waiting for Mapleprimes" in my browser's annunciator box: and I wait, and wait, (as in >5 minutes) and still this step does not complete. Just to be annoying, every once in a while the file will upload as normal, such but success is now the exception

I'm seeing the same issue in Firefox 45.0.2 and Chrome 50.0.2661.75mon Win 7, 64-bit.

Anyone else seeing the same issue?

 

 

I am currently working on FDM ,i have 2 coupled nonlinear pde ,i need help in solving these equation using maple code.

> PDE2:=eta^4*diff(theta,eta,eta)+2*eta^3*diff(theta,eta)-Pr*(f*eta^2*diff(theta,eta)+S*diff(theta,tau))=0;

 

The code I write is properly indented.  The operation of pasting it here strips the white space and makes it hard for the reader to comprehend the structure. Manually restoring the appropriate indentation is doable but tedious, made more so because the characters we see here are in a variable width font.  The rationale might be that, given a variable width font the indentation is going to be inconsistent, but that isn't the case if the preformatted style is used, which I do, for code.

Is there any way to turn off the white space stripping?  Presumably this is some ridiculous xml-based processing feature.
