Read and write English  is a strian!

    My first touch with Maple was in 1997,when I was in my undergraduate course.The software of maple was in three floppy disk.

    Since 2000,I becomes a teacher for mathematics .Now I am using it to compute the integrate,limits,etc.

To the world you may be one person,but to one person you may be the world!

Just a suggestion to make it easier to determine wether a question is still open or has been answered.

I have noticed there are many questions that have not been answered throughout mapleprimes history so here I am suggesting that a small yellow circle in front of the question denote an open question and a small green circle to represent answered questions.

Sometimes I come across unanswered questions, and it is still open but looks like it could be answered. ...

This post is a further development of my earlier question in reply to John's post. I have implemented a basic version of the CANDECOMP/PARAFAC algorithm referred to on Wikipedia and described 

This is not really the next part in my randomness series, but more of an aside.  I used Maple's embedded components to use the Lotto649 drawing data from my last post to create a historical lottery simulator.  Basically, you fill in your prefered numbers, and it simulates you playing the lottery in every draw since 1982.

There are a few ways to view the source of a Maple procedure, such as by using the commands  showstat and print. And these work as usual for the exports of a module. But for procedures which are declared as local to a module these methods do not work right away since by default modules' contents are opaque.

One way around this is to change a setting, by issuing kernelopts(opaquemodules=false) prior to attempting...

Click Maple Math, enter x^2/(1+x).   The Preview disappears as soon as I press "/", and the result is not pretty-printed.

I selected the whole document and expanded the document blocks. There near the top of the document were nine copies of "plots[interactive]()" all in a row. Deleting them fixed the problem. Seldom is a fix so easy. Many thanks.

In this series of blog posts, I have picked on Baseball win-loss records already.  Looking for other sources of things that might or might not be random, I decided to look at lottery draws.  Since I live in Canada, the obvious lottery to look at is the national Lotto 6/49.

A lotto 6/49 draw consists of drawing 6 numbered balls from...

If you want to know what ::uneval does (it's an advanced option for procedure parameters), you can look at the uneval section of ?parameter_modifiers.  It is useful when you want to write a function which works on raw user input rather than on evaluated input.  This is quite tricky, and fraught with danger, and should only be used as a last resort;  but sometimes it really is rather handy.

Under the Recent tab where you select Your Contributions.  It does not show all my posts.  Why is that?

Specifically, one example, my post on Wordle is not shown when I select My Contributions.  The only way I can see it is if I use All posts.  Please fix.

If you are interested in listing to me ramble for an hour about integration algorithms, it looks like the recording of the Webinar I gave in early September has been posted to the academic webinar archive: Theory and Practice of Symbolic Integration in Maple. I tried to make it a broad introduction for someone with...

I've been making some use of the Maple Cloud for a while now, and thought that I'd share some comments.

So far, it's been quite useful to me, and I like it. This surprised me a bit. I expected not to find it useful, and to dismiss it with an old-timer's "Bah, humbug... as useless as Maple+twitter!" But, to the contrary, I've found a use for it; a need that isn't otherwise...

It's a new school year and traffic is up.  Just wondering what happened to the student maple forum?

Also as a suggestion, some forums have sticky's, a post that stays at the beginning of the forum where users can generally find welcome information and helpful starter hints, yes it's impossible to cover everything but something would be nice for the new users. 

Is there a way to get told only once that  "There are new updates on www.mapleprimes.com that match your notification subscriptions:" ?

I always receive 3 (when I do get any), and yes, they are identical.

3 times is better than 0 times, though.
