Graphical Expression Viewer is a graphic instrument especially designed for users who often work with mathematical terminology. Graphical Expression Viewer lets you represent and view mathematics of the type z=x*sin(y).
In Graphical Expression Viewer you just have to indicate the range and automatically it generates the graph applied to this function.
Once the graph has been generated, you can move it with the mouse from one side or the other, and you can also rotate it various degrees. To be able to use Graphical Expression Viewer you need a 3D card that supports OpenGL.
