Introduction

The Magma package introduced in Maple 15 includes the command Enumerate. This routine allows you to count, or list, isomorphism class representatives of magmas of a given (small) order satisfying a selection of properties that...

The ongoing spam problem has made this site unusable. Even after spam is removed, it's effect on the "recent" pages persists. This is a months-old problem.

And after over a year the site still has no good support for displaying mathematics, or for entering 2D Maple input.

And there is no indication of any clear and concrete plan to properly address either of these problems, despite repeated requests and inquiries by members.

Hello:

I'm studying many time ago the quantum chemistry of rectivity . so far, I can arrive to news theories from my experince on Maple productcs as they are incorporated in my theoric equations. I have glad  on communicat my previous results on Chemical Reactivity and Uniffied Field. botn of those ara closely related and my purpose is obtain diffusion and comments on these.

- My first paper was on Chemical Reactivity (Kinetics and Dynamics) and...

Here is the progress made in the investigation of what I call the convergents constants:
https://oeis.org/wiki/Table_of_convergents_constants

I wonder if anyone would be interested in adding anything to it. I would like to see the convergents constants studied some in Maple to compare with my Mathematica results; my investigation is in dire need of some proof other than my...

Most of the time I don't know what or why things are happening here on the mapleprimes site. 

I don't want it as a post or question as it gets shuffled down and is useless later on anyway. 

I would like a news section to inform me and everyone else of what is currently being worked on (ie the site programmers are currently working on ....  currently tags for posts are being updated), what is currently happening (spam attack - although this seems to be on the upswing lately...

Hello all,

I've noticed that something has changed to the type of sqrt in Maple 15, which breaks backward compatibility...

In Maple 14, we have

> type(sqrt,procedure);          true
> type(sqrt,`module`);          false

> eval(sqrt);          proc(x::algebraic, f::identical(symbolic))  ...  end proc

while in Maple 15, we have

> type(sqrt,procedure);          false
> type(sqrt,`module`);          true

Following Christopher2222 request, I wrote the following procedures for "exact" cubic Hermite spline interpolation,

p:=proc(x0,p0,m0,x1,p1,m1,x)
local t,d;
d:=x1-x0;
t:=(x-x0)/d;
p0+(d*m0+(3*(p1-p0)-d*(2*m0+m1)+(2*(p0-p1)+d*(m0+m1))*t)*t)*t
end:

pb:=proc(x0,p0,x1,p1,m1,x)
local t,d;
d:=x1-x0;
t:=(x-x0)/d;
p0+(2*(p1-p0)-d*m1+(p0-p1+d*m1)*t)*t
end:

pe:=proc(x0,p0,m0,x1,p1,x...

This is for Spanish speakers only. Not related to Maple, but related to Math. The Spanish newspaper El Pais has a series of videos on various math problems, together with solutions (posted later), it's set up as a sort of competition but just watching is (usually) great fun. You can access the full archive online.

You probably don't need to know much Spanish to follow the problems. Much is illustrated in writing on a black or white board. If you don't speak any Spanish...

Only answers and comments to the question are counted and adding them leads to moving the question up.

Although the source is very old (Maple 6) the topic is interesting.  Should one come across the webpage Analysis and Synthesis of digital sound samples with Maple 6 located here http://www.maplesoft.com/applications/view.aspx?SID=3940&view=html they may have a dissapointing maple browsing experience when 3 of the links they try to access are broken and not available.  

After Poker's Black Friday (April 15), I started to think about moving to Canada, and I realized that I know very little about our northern neighbor.

I would appreciate any suggestions about a nice place with not very expensive rent (for a handicapped accessible house), safe for living, with a (very) good Internet connection, not very far from shopping places (do you have Walmarts?) etc.

Being close (in, say, 50 miles or less) to a casino with a poker room is desirable, but not absolutely necessary.

Thank you,
Alec

   The Kolmogorov-Smirnov test is a widespread, simple, and effective test to check the hypotheses of the form H[0]:=F[ksi](x)=F(x), where a function F[ksi](x) is the CDF of a population distribution, a function F(x) is a given continuous function (the Kolmogorov  test), and the hypotheses of the form  H[0]:=F[1](x)=F[2](x), where F[j](x), j=1,2, are the CDF of two population distributions, both are assumed to be continuous (the Smirnov test).  See the ...

A Plot Component (on the right below) can act as a kind of 2-dimensional "slider" for inputing values of two parameters at once.

The polar plot (on the left below) makes use of both values.

If you click in the right Plot, and drag around the mouse cursor for a while, then the left Plot will be continuously updated.

Make sure to execute the collapsed code-edit region, to initialize it. (Just click on it, to execute. Or expand, look, and right-click on it.)
