ZGrapher is a simple graphic utility. It can be helpful for any user, from a schoolboy to a professional mathematician. Using this program you can plot graphs of the following types: Y(x), X(y), R(a) – in polar coordinates, X(t) and Y(t) – parametric equations and graphs of tables. To create a graph you should specify its parameters – formula, graph’s width, style, color, intervals - and ZGrapher will make the rest. If you don’t like the results, you can use the editing function and change shapes, colors and lines. Besides, the program allows you to add comments, text labels, points and legends to your graph in different colors and fonts. All the objects – graphs, coordinate plane axes and coordinate space are fully customizable. The amount of graphs in one document is limited only by the amount of the free memory.
Moreover, there is a calculus feature, which allows you to obtain derivatives, equations of tangents and normals, numerical integration and perform regression analysis. The results can be copied and exported to Word and also can be saved in BMP, GIF and PCX image formats. The “Tip of the day” option will provide you with a helpful hint.
