Open source cross-platform software of geometry, analysis and simulation - Yves Biton

# MathGraph32 Presentation

publication Saturday 7 June 2008.

MathGaph32 is a free software for dynamic geometry and analysis figures.

MathGraph32 was created and is still maintained by a french Mathematics teacher, Yves Biton

The Java version est free under GNU GPL3 license.

MathGraph32 is available in three langages : french, english and spanish.

MathGraph32 allows the use to create in a few mouse clicks pure geometry or analysis figures.

With MathGraph32 you may also simulate random experiences.

MathGraph32 allows the creation and graphing of your own numerical functions (of a real or complex variable of one, two or three variables). You can also calculate the formal derivative of a real function ou a partial derivative function of a function of some variables and many other things.

You can also graph recurrent sequences graphs, real or complex.

Usual geometrical transformation are also available, including direct similitudes ans inversion.

MathGraph32 was created by a teacher. That is the reason why it offers many features not present in other softwares such as :

The ability to create segment and angle marks (including oriented angle marks).

The ability to measure angles (oriented or not).

- The ability to work in degrees as well as radians.

The ability to cancel or redo actions with a depth of 50 actions.

A full coverage of complex numbers and graphing of complex numbers.

The ability to create object locuses (MathGraph32 exclusivity).

Macros which are buttons you can click on to launch an action on the figure, such as hiding or displaying objects, launching animations and many other features very useful for teaching purposes.

Dynamix LaTeX displays (which can be linked or not to a point).

The ability to include in a figure formula editors allowing the change of formulas directly on teh figure (working also online)

The ability to export your figure in a web page using only html and JavaScript (applets are alos available).

MathGraph32 allows the user to create macro constructions.

You can create your own contructions and also use predefined constructions.

For instance, special constructions allow the creation of pseudo 3D figures.

MathGraph32 creation was a tough piece of work.

If you appreciate it, please make it known. MathGraph32 is free of charge.

I wish to you a happy use of my software.

Examples of figures

You can capture M and N points or launch the animation macro.

Click on the macro on the right size (in french sorry) to hide or see the curves and to launch an animation.

You can capture $\theta$or click on a macro to get it executed.

Click on the macros at the top of the page to launch random experiences

This figure shows the image of a square through a complex transformation. You can change the function formula directly on the figure. You can also capture points A, B and M and also modify the n value by clicking on buttons + and -.
