*

The developer team of *WMI2 <http://matek.hu/>* is happy to announce their
continuously developed e-Learning software which reached the milestone
version 2.1. This new version is capable to provide about 70 selected
symbolic and numerical operations from a wide range of areas of mathematics.
The targeted audience is college and university students at the age of
14?21. Besides solving equations or plotting 2 and 3 dimensional functions,
*WMI2* can also differentiate and integrate, moreover factorizing and
expanding of expressions are also built in. *WMI2* has a clear user
interface allowing the user to see his input and output formulas in a
worksheet which can be saved or printed at any time. *WMI2* also has a
background database of private mathematics teachers offering commercial
support if a student is in a need.

Kovacs<http://wmi.math.u-szeged.hu/%7Ekovzol>and Robert
Vajda <http://www.math.u-szeged.hu/%7Evajda>; are members of the research and
lecturer staff of University of Szeged <http://www.u-szeged.hu/>;, Bolyai
Institute <http://www.math.u-szeged.hu/>;. *WMI2* is currently available in
English and Hungarian, based on the Maxima <http://maxima.sf.net/>; computer
algebra system, the gnuplot <http://www.gnuplot.info/>; function plotting
tool and the formconv <http://formconv.sf.net/>; formula converter. Hardware
support is provided by Part?ci? BT. <http://particio.com/>;, a Hungarian
software company committed to Linux based development of mathematical
software.

Version 2.0 of *WMI2* has been published world-wide in October 2007. It has
been being reached by about 100?150 hits per day and served about 5000
different calculations in selected areas of mathematics. *WMI2*, which is
free of charge, was supported by the Hungarian Ministry of Information and
Communication in 2003. Version 2.0 and 2.1 was supported by the Ministry of
Education, Taiwan.
