GraphingCalc draws 2 dimensional and 3 dimensional graphs from algebraic equations to give students a better understanding of math. Graphs can be rotated, sized, moved, zoomed, and colored with the mouse. Up to 3 graphs can be drawn at the same time, which is useful when studying intersections, asymptotes, derivatives, and differences between similar equations. Graphs can be animated with a time variable, T. Graphing with polar coordinates in two dimensions and special functions for Fourier Transform analysis are also supported. Version 2.1 may include special functions for Fourier Transform analysis. These are very advanced functions and include step, sgn, rect, ramp, tri, sinc, and gaus.
Editor's review of GraphingCalc Visualize the graphics While this demo program acts more like a slide show than a worksheet, its impressive graphic displays and customization features are enticing enough to invest in the full program. GraphingCalc takes algebraic equations and graphs the results in either 2D or 3D grids.

The program interface, while not aesthetically pleasing, is functional and straightforward. 3D images can be rotated with just a mouse click, at any speed, and in any direction. If you hold down the right-click button and move the cursor up or down, you can zoom in or out on any graphic. Color and other display settings can all be customized from the main program menu. For graph specifics, you can click check boxes to hide or show individual panels of a graph in further detail.

The main drawback of the GraphingCalc demo is you can't enter your own equations. The program comes with a set group of equations for viewing. Yet, there's no time limit to using the demo version, so it's easy to get a good sense of the program's capabilities before taking the plunge. Overall, this appears to be a useful program for students struggling with algebra or for those who simply want to get away from grid paper and pencil.
