    I was able to view them last night. 

    So there is a maximum number of conditions that one can set... good to know!

    I tried your solution, and it does work. I'll just have to determine the values of my b1 and b2 parameters with a little programming.

     

    Thank you very much!

    Classic Triangle Peg Board GameIn high school I was briefly fascinated by a triangular "jump all but one" game, commonly found at Cracker Barrel restaurants.  The basic premise is that any peg can "jump" over an adjacent peg to occupy the empty hole next to the jumped peg.  The jumped peg is then removed.  The goal is to continue jumping pegs until there is only one left.  


    The instructions on the face of the Cracker Barrel version of this game say, "LEAVE ONLY ONE -- YOU'RE A GENIUS".  Wanting to claim the right to call myself a genius, unlike ordinary kids, who might just play the game a few times, I sat down on my Turbo-XT and started writing BASIC code.  The algorithm I came up with ran a bit slow, so I directed output to my printer and let it run over night.  In the morning the program was still chugging along.  I advanced the paper feed on the dot-matrix lineprinter -- the kind that used continuous feed paper with perforated edges and holes on each side.   Into view came 3 solutions represented by a string of numbers.   A quick check verified that I was now a genius.  

    Now that Maple 15 is out, I thought I should share this little application I made: GoalTracker.mw. It is an application partially inspired by the BMI tracker in Nintendo's WiiFit application; you could easily use it to track a weight loss goal. But it could also be used to track other quantifiable goals. I am posting it here mostly because it takes advantage of two new features in Maple 15.

    Ukraine-2011. The State Final Certification in Mathematics

    What must be able to solve a graduate of the Ukrainian school in 2011?
    31 variant assignments.
    Currently:
     1. Assignments reformatted in Maple.
     2. Created an interactive...

     Work plan for the Russian Maple Application Center in 2011.

     1. Popularization of the new features of Maple 15.
     2. Popularization of educational MAC-articles.

     3. The transformation of the most popular Russian-language Internet maths textbook to the business card of Maple.
     4. Further approval of Maple as the best assistant in preparation for the delivery of the Single State Exam (Russia).
     5. Further approval of Maple...

    In the new Maple 15, if any calculation or process requires more than a few seconds, the cursor does not change to the hourglass (or equivalent) symbol. This makes it difficult to tell whether anything is happening and gives the impression that the program has hung.

     

    I suggest that the hourglass (or equivalent) be resurrected whenever anything takes more than a few seconds.

    The (new, Maple 15) Programming Guide is available for download from the Documentation Center.

    This page from the Online Help suggests that GMP 4.2.1 is still being used in Maple 15.

    But the latest "stable" release is GMP 4.3.2, see release notes here (various fixes and improvements in the 4.3.xx series mentioned).

    Perhaps this could be updated in a service release Maple 15.xx.

    What happened to all the Maple 5 applications at the maplesoft application center? 

    Why just the other day I was looking at them.  Very dissappointed to see them "removed".  In particular a series of applications for mapping. 

    The drop down option for Maple5 has dissappeared. 

    Are they gone?  Can you put them back?

    Since -1 = i^2 I thought that there could be some meaning behind "alternating" series that instead of beginning with (-1)^n begin with (a+b*i)^n, with real coefficients, for abs(a)<1 and abs(b)<1. I'm not sure but it seems that such series are absolutely convergent, because (a+b*i)^n -> 0+0I as n->infinity, hence the term utterly diminishing series instead of alternating series.

    As an example,
    Where sum((-1)^n*(n^(1/n)-1),n=1..infinity)= 0.187859642462067120248... ,


    It still seems that the original post won't accept new replies, so I'm starting a new post.

    On the topic of the quality of rendering of (2D) Math on websites, could that also be re-examined for both Mapleprimes and Maplesoft's on-line help system?

    Right now the on-line help has pages with missing images in Examples. For example, the `int` and `sum` on-line help pages, here and here.

    On that

    The maplecloud may in some respects reduce the sharing of applications on mapleprimes and at the maplesoft application center.  A maplecloud user may instead of sharing his application via mapleprimes applications or the maplesoft website may just make his worksheet publicly available over the cloud simply because it's easier to do. 

    It is true that mapleprimes is a different type of serviece that allows the interaction of ideas/questions as well as the sharing...

    Mapleprimes takes unusually longer to load than used to.  And some people complain about being emailed 3 x's I'm not sure it's fixed but I've noticed my page actually loading 3 times before it actually comes up.  I'm on dial up so I can notice things people on high speed won't notice.

    One other thing possibly very important to the web program designers of this site.  If I load the mapleprimes web page and say stay offline, it does this 3 times. ...
