## A glimmer of light

This is the kind of thing that can drive a beginner crazy. The behavior of the engine changes as a result of including different libraries. The engine isn't extended, it is changed. This makes for a very tough learning curve.

## MapleStudio the next step - plotting complex ...

by: Maple

With this Generation of MapleStudio you can also plot complex functions in 2D and also 3D. For doing this, MapleStudio uses the conformal and the conformal3d comands of Maple 10. The following example will show you, how it works.

## mapleSTUDIO or make plotting easy to use

by: Maple

With mapleSTUDIO you can plot functions in 2D and 3D. Animating your plots won't be a problem any time. This is the easiest way to plot your functions.
You can use it here online on mapleNET or you can download it and run the worksheet on your Computer. For adding new components to this worksheet I will only change the file on mapleprimes, but the name and the URL will be the same. So you should bookmark the mapleNET-URL for using the newest version of mapleSTUDIO. You can also add my Blog to your Feed-Reader, so you will know, when a new version is available.

## Systems of congruence

by:
I'm working on entering in congruence for entering UPN (or UPC numbers)and maple does not acknowledge the first digit if it is a 0 entered. Anyone know how to fix this problem?

## Online Plotting with interactive worksheet

by:

The following interactive worksheet gives you the possibility to plot functions in 2D and 3D. There is also an interactive version available on the MapleNET - Server. You find it here. You can also download the worksheet here and run it in your Maple.
I will try to publish further versions with more possibilities to plot in the next weeks.

## How to plot the area bounded by { f(x), x=a, x=b...

by:
To anyone: Will someone provide maple syntax to plot the following lines f(x), x=a, x=b from x=c..d where f(x) is an explicit function and x=a and x=b are vertical lines and the extend of the graph from x=c to x=d. This should give me the graph of the 3 equations from x=c to x=d. I tried implicitplot, graph it led me nowhere. Many thanks PV

## Occurences in Pi

by:
After read this funny post by Will, I implemented a short function in Matlab (linked to Maple) to count the number of occurences of any number into the 10.000 first digits of Pi. Here is the result for the first 9.999 numbers:

## Jim Herod's Lectures on Hilbert Spaces for Science...

by: Maple
MaplePrimes own Jim Herod has a wonderful set of lecture notes—accompanied by a collection of Maple worksheets—which introduce linear operators on infinite-dimensional Hilbert spaces to beginning graduate students in science and engineering. Entitled Linear Algebra, Infinite Dimensions, and Maple, these notes were developed from a one quarter course which Prof. Herod taught many times at the Georgia Institute of Technology. The notes are very concise and have been refined and improved many times over the years in response to student feedback.

## Knots

by:
Take a piece of string — I mean literally, go get a piece of string and tie it into a knot. Now tape the two ends together so it makes a closed loop — necessary to fulfill the mathematical definition of a "knot." How many different knot types do you think there are? The number is infinite, and the question of how to categorize these manifestations of loopiness has engaged some of the finest mathematical minds for a century. Original story

## Maplets for Calculus

by:
Maplets for Calculus is a collection of maplets designed to help students practice their calculus problem-solving skills and to assist instructors in providing effective classroom demonstrations (including 2- and 3-D visualization -- even animation). The maplets cover all major topics in single-variable calculus - limits, derivatives, integrals, differential equations, sequences, series, and polar coordinates. Some of the maplets help to build intuition and some provide practice with routine computational techniques. An individual license for Maplets for Calculus is available through the MapleConnect program at . Lab/Classroom bundles and site licenses are also available. The complete list of maplets and sample videos may be seen at .

## The Math Rap

Here is a nice video that "might" be helpful to students learning about Pi. It is a rap music video created by a public television station in Boston. It has to be seen to be believed, and it is quite funny.
