  • Does anyone see the Maple 2D Math output in the replies to this post?  What I see is a lot of Maple Equation markers.

    A certain "competitor" to Maple has started offering a "Home" Edition of their product for a very attractive price...I use Maple at work, but love to tinker with individual research.  Supposedly, this edition is the same full-featured product as the commercial and academic versions.  A "Home" Edition of Maple would be *awesome*.  I'm not prepared to jump ship to that "other" product, given the knowledge capital I have of Maple, but I've started entertaining the idea...

    How the badges are updated? Is it done manually?

    In particular, I voted many posts up (Thumbs Up), used 2D-math more than 5 times (2-Dimensional), left more than 10 comments (Commenter) etc.



     

    Has the 'tabbing nuisance', as reported in I declare defeat: rolling back to Maple 9.5, been resolved in Maple 12+? And what about the 'XML-contamination', as also mentioned?

    PS: Congratulations to MaplePrimes for a visually very appealing interface. With the migration to this new interface, I have finally been able to gain again access to my account, this partly explaining...

    How about allowing members to add tags to others' posts/questions?

    It could be done without too much risk of vandalism. It could require a certain reputation to be enabled. Or it could allow only addition of tags and not removal. Or it could allow adding tags only from the preexisting tag list (or, getting fancy, the full list from a few days earlier).

    There is a huge volume of very nice old posts buried in this site. Without tags, it will be much harder to...

    Quite a few of the Questions under the "Unanswered" tab on the Mapleprimes main page, down around the end of the first page worth of results, do actually contain Comments.

    It looks like such responses were not migrated properly as Answers.

    Joe Riel once posted a very nice post about a package named "tine" that he wrote to measure performance in Maple.

    It is cached here by google.

    If a function is differentiable at some point c of its domain, then it is also continuous at c. However here we extend the notion of differentiability to be valid for individual points on the real number line, specifically positive integers.

     f(n)=(-1)^n* n^(1/n)

    THEOREM MRBK 8.0

    f=f' / (I*Pi+(1-ln(n))/n^2)| n ∈ {1,2,3,...}

    By THEOREM MRBK 4.0, When n is in the set of (positive) integers the derivative of f is exactly I*Pi*f+(1-ln(n))*f/n^2.

    So f' = I*Pi*f+(1-ln(n))*f/n^2| n ∈ {1,2,3,...}

    Solving for f, we have the following:

    f' = I*Pi*f+(1-ln(n))*f/n^2

    f' = f*(I*Pi+(1-ln(n))/n^2)

    f=f' / (I*Pi+(1-ln(n))/n^2)

    Points and lines, and the relationships between them, are essential ingredients of so many problems in, for example, calculus. In particular, obtaining the equation of the perpendicular bisector of a line segment, dropping a perpendicular from a point to a given line, and calculating the distance from a point to a line are three tasks treated in elementary analytic geometry that recur in the applications....

    I spend much of my time traveling for business. These trips often last a week, and we try to visit as many potential customers as possible, and in the most efficient order. This involves matching our hosts' calendars with our own, booking the most cost effective travel options, and coping with last-minute cancellations and changes. It isn’t easy!

    This has become so much easier with the advent of shareable calendars and mapping services, like Google Maps. ...

    I've just published an update to MaplePrimes that fixes a few minor bugs and adds one new feature:

    • Your Bio is now displayed on your profile page. This can be edited on your edit profile page
    • The paging between Answers, Questions and Posts on a user's profile is now working.
    • The rendered image from the 2-D math button is now up 300px wide, which should cause most math to appear better.
    • When creating a post, the date is now stored correctly instead of 4 hours off as it was before.
    • The "Mark Page as Read" button now works on the Recent tab.

    A long while ago, I wrote a couple posts (part1 and part2) about mining data from the US SSA website.  I subsequently adapted the code from those blog posts into a visual application with sliders and interactive plots.  If you have played with the new ?MapleCloud functionality in Maple 14, you may have seen it posted already.

    Several of my posts were voted up or down, and I couldn't see who did that. It would be a useful feature to be able to see who voted posts up or down - at least for your own posts.

    When I want to look through somebody's (including my own) posts, who has several pages of them, neither clicking the arrow nor clicking another page number works - even if the new page says something like page 2 of 6, or page 3 of 7, it shows exactly the same posts that were on page 1.
