I have been working with Newton-Raphson fractals for some time.  Like others it was necessary to deal with the "black areas" many times, so I performed some additional analysis and present some of these results here.  This will allow others to stop coloring these areas black and allow visualization of the structure inside these areas.  It will also help demonstrate...

One of my coworkers brought in G.L. Legendre's book "Pasta By Design" (amazon.ca/dp/0500515808).  It is full of photographs and parametric equations for 92 shapes of pasta.  Of course, we had to set about plotting his equations in Maple.  Orginally I was going to post about this before Maple 16 came out, but I was struck with how much better plots looked in the Maple 16 pre-release and so I decided to wait.   As one example, here are the parametric equations for Giglio Ondulato noodles plotted using the default 3D plot settings in Maple 16 and Maple 15.

I was introduced to the geometric interpretation of correlation and linear regression recently.

Orignially due to the famous statistician R.A.Fisher, the idea is that the correlation between 
two variables is the cosine of the angle between the 2 vectors in n-dimensional space.
This can be demonstrated in Maple as follows:

First, we represent each variable as a vector and transform it so that it is centred at its
mean and has a length equal...

All critics and new ideas would be appreciated.

N.B. The MaplePrimes site elided everything past the bullet list, which included more description and links for obtaining the package.  It appears as though bullet lists break MaplePrimes, so this is going to be a bit out-of-order.

This new debugger uses a client/server architecture.  Communication with Maple is via TCP. This permits remote debugging as well as concurrent debugging of multiple Maple processes.  That is useful for comparing different...

This is one of rank tests.
Non-parametric methods are widely used for studying populations that take on a ranked order (such as movie reviews receiving one to four stars).
The use of non-parametric methods may be necessary when data have a ranking but no clear numerical interpretation, such as when assessing preferences.
In terms of levels of measurement, non-parametric methods result in "ordinal" data.
After the introduction to the topic let's turn to an example.

I created a procedure over a year ago to collect earthquake data from the usgs and save it into a file. The procedure pulls data off the internet and saves it in a text file with a date stamp (minus the year - because I haven't been bothered to change it ) in the folder location f:/7 day earthquakes.  Feel free to modify it as you wish.  Here it is, pretty much still in it's original format when I created it.

Dr. Gilbert Lai is a mentor for the FIRST Robotics team SWAT 771. He is helping an all girls team from grades 7-12 design a basketball-shooting robot for this year’s annual FIRST Robotics Competition. Dr. Lai is using MapleSim and Maple to help the team understand the principles involved and design their robot. This blog post is part of a series that chronicles the progress of the team.  Posts in the series include:

Problems concerning integration have been discussed on  maple primes  before with piecewise continuous antiderivatives explaining  difficulties. Here an example is given using Maple 15 where a continuous antiderivative is returned but definite integration fails to give the correct answer.

In case if you like notepad++  under windows, and still didn't do smth like that then this is for you .userDefineLang.zip

Unpack to notepad++ folder. In case if you already had had other
own language then just copy "Maple language" section.
