Grafici 2D 1.1.1 is created to be a simple but effective application that allows for graphing any kind of function in one variable f(x) or in parametric form y(b), x(b). You can also plot more function in one graph and calculate the functions f(x) for a desired value. Moreover it's possible to plot the graph of the derivative of a function, display the relative max and min, the intersections with the axes and makes the zoom of a selected part of the graph.

Requirements: Microsoft .NET Framework 2.0

File Transfer is an application that allows you to connect to your friends computer, and transfer fast and secure any file or folder.
File Transfer uses a direct P2P connection, that ensure the fastest possible transfer speed between the two computers.
File Transfer is extended with a NAT traversal protocol and is able to directly connect even behind NATs and firewalls. Try it, youll never want to use something else for transfering files!

Small Math 2D is application for visualization of two-dimensional mathematical objects written in Java. By now, it is in a very early stage of development and provides only a small fraction of future features.
Yet, it can plot functions of one variable, parametric curves, implicit curves, dynamical systems defined by recurrence, ordinary differential equations (initial problems) and systems of two ordinary differential equations of any order (initial problems). Soon, new features will be added, among them: contour plot, colored height maps, complex numbers, inequalities and many more.
