Graphing Calculator 3D is a Education::Mathematics software developed by Runiter Company. After our trial and test, the software was found to be official, secure and free. Here is the official description for Graphing Calculator 3D: Easy-to-use 3D grapher that plots high quality graphs for 2D and 3D functions and coordinates tables. Graphing equations is as easy as typing them down. Graphs are beautifully rendered with gradual colors and lighting and reflection effects. Both cartesian and polar coordinates are supported as well as parametric equations. Fast rotation and translation of graphs with the mouse and with animations make graph visualization easy.<p>The intuitive user-interface is designed with frequency of use in mind. Equations are instantly plotted as you type them down and after each key stroke. The frequently used tools and options are only one click away. Value table for x-y-z coordinates can be generated, modified and re-plotted instantly.<p>- Plot regular and parametric equations.<br>- Plot coordinates tables.<br>- Instant quick plotting after each key stroke.<br>- Cartesian/Polar coordinates in 2D.<br>- Cart/Cylindrical/Spherical coordinates in 3D.<br>- Rotate and zoom in the graphs in real-time.<br>- Shade 3D graphs for optimum visualizations.<br>- Fully customizable axis.<br><p>The following platforms are supported:<br>- Windows 32bit & 64bit (95/98/NT/Me/2000/XP/Vista/Windows 7)<br>- Mac 32bit & 64bit (10.4, 10.5, 10.6)<br>- Linux 32bit & 64bit (All that support Java 5.0+)<br> you can download Graphing Calculator 3D free now.
