MaplePrimes Questions and Posts

These are Posts and Questions associated with the product, MaplePrimes

We added a small new feature to MaplePrimes that will make it easier to tag other members in your questions, posts and comments.

To use the feature, type "@" in a message. If you wait a moment, a list of names will be populated, starting with members who are participating in the current thread, followed by other members ordered by reputation. You can also begin to type after the "@" to search for a particular member. Similar to the above, members who match your search who are in the current thread will appear first, followed by others.

If you are tagged in this way, an indication will appear in your notifications pane.

We hope you find this new feature useful!

 

how do you answer people's questions on here to get the points?

Try More/GeneratePDF  in  the menu under  a post/question. See screen_26.09.17.docx as an example of a result. Also Adobe Acrobat Reader fails with it. That was submitted to MaplePrimes staff through the Contact  button at the bottom of this page. I obtained no feedback from them.

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.

there is a problem with users tab and web page of mapleprimes, and it just does display the first page and not other pages ...
for example :
https://www.mapleprimes.com/users/?page=2
is not displayed ...

There is a problem with mapleprimes favorites. 

Looking at my list of favorites it cites I have 6 pages, however when I get to page 3 it shows a list of only six items and no more page listings after clicking the back button and going again to page 3 even less appear.  I was looking for specific questions and posts I have favorited which seem to be abscent from the listing. 

Can mapleprimes administrators please address the problem?

This is Maple:

This is a 3900 digit prime number. It took me about 400 seconds of computation to find using Maple.  Inspired by the Corpus Christi College Prime, I wanted to make an application in Maple to make my own pictures from primes.

It turns out be be really easy to do because prime numbers are realy quite common.  If you have a piece of ascii art where all the characters are numerals, you could just call on it and get a prime number that is still ascii art with a couple digits in the corner messed up (for a number this size, I expect fewer than 10 of the least significant digits would be altered).  You may notice, however, that my Maple Prime has beautiful corners!  This is possible because I found the prime in a slightly different way.

To get the ascii art in Maple, I started out by using to import ( )  and process the original image.  First then and to get a nice 78 pixel wide image.  Then to make it a pure 1-bit black or white image.

Then, from the image, I create a new Array of the decimal digits of the ascii art and my prime number.  For each of the black pixels I randomly use one of the digits or and for the white pixels (the background) I use 's.  Now I convert the Array to a large integer and test if it is prime using (it probably isn't) so, I just randomly change one of the black pixels to a different digit (there are 4 other choices) and call again. For the Maple Prime I had to do this about 1000 times before I landed on a prime number. That was surprisingly fast to me! It is a great object lesson in how dense the prime numbers really are.

So that you can join the fun without having to replicate my work, here is a small interactive Maple document that you can use to find prime numbers that draw ascii art of your source images. It has a tool that lets you preview both the pixelated image and the initial ascii art before you launch the search for the prime version.

I'm wondering if there is an available command that can evaluate the number of terms required to produce a desired outcome.

Specifically, I am interested in determining the probability of a Poisson distribution, given the parameter (mean) value and the probability outcome. I can obtain the desired result using trial and error / brute force, but I am curious to know if there is a more efficient way. 

Suppose that, lambda = 2.6 and the cumulative sum of the probabilities is 95%. I know that I must add the first 6 terms for P(x) in the series (x=0,1, ..,5) to sum to 0.95. Each term ...  P(x=0)= 0.07, P(x=1)=0.19, and so on.

However, how can we know that desired 95% outcome can be determined from the first 5 terms without trial & error?

 To Whom It Might Concern,

I purchased Maple on Jun 5, 2017 for my Window laptop. However, my harddrive in my laptop was broken and i lost all my stuff including Maple. I am using my husband's laptop right now. How can re install Maple? I still have the transaction number (removed). Would you let me know what I can do to re-install the software? Also, my husband's laptop is a Mac. 

I am looking forward to hearing from you.

Nancy Phu.

Good day sirs,

I am trying to plot graphs on stream function but its given me a lot of multiple error using my codes. Anyone with useful information should please share. 

Below is the code.

Thanks

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?

Earlier today, we published an update that improves the way MaplePrimes handles tags.

New features include: 

  • There are now tags for Maple Commands and Maple Packages. These tags are denoted with special icons, and cannot be edited. The hope is that these special tags will be useful to anyone looking for assistance with a particular command or package, and will provide another centralized location to find support. For example, a command tag for the plot command will look as follows:.  A package tag looks like:
  • The tags page has been completely updated to show tag use over time, and also provides information about specific tags. Users with moderator privileges can also edit tags directly from this page.
     
  • Hundreds of inappropriate or 'garbage' tags have been removed.

 

In addition to the changes to our tagging, we made a few other improvements and updates, including:

  • New academically- and techically-focused social networks have been added to user profiles
  • Updates to the message editor to improve WYSIWYG consistency
  • A variety of smaller fixes and improvements

I hope you find these improvements valuable, and look forward to your comments and suggestions for future improvements.

 

I noticed Mapleprime have entries of users who clearly create an account just to put a bad website URL in there and they are just spam.

Why do not the moderators of Mapleprime purge these out? Mapleprime is full of these spam marketing users.   Here are just few I found in few clicks

http://www.mapleprimes.com/users/Frenettees8d
http://www.mapleprimes.com/users/Ingegneriaq7r
http://www.mapleprimes.com/users/Inabinetaq6s
http://www.mapleprimes.com/users/Bruggemanse5l
http://www.mapleprimes.com/users/vito5854
http://www.mapleprimes.com/users/deblogepa
http://www.mapleprimes.com/users/organicjunk80

There are hundereds of these spam URLS in there. They make an account, only to add their infected web site URL there so if someone clicks on it they get virus.

Moderators of mapleprime should do better job and remove these cleary spam entries from Mapleprime.

on what grounds do posts get deleted from this website? like i just dont see the problem if its non offensive and math related to be honest it just seems a bit ridiculous to regulate content to that extent
