ZigZag is a handy tool to plot and explore math functions.
Features:
Supported graph types:
1. Y(x);
2. X(y);
3. graphs of tables;
4. R(a) - in polar coordinates;
5. X(t) and Y(t) - parametrical equations;
You can specify color, style and width of lines for each graph. You can also change additional properties of graphs depending on graph type (e.g. amount of plotting points, plotting intervals, etc);
The amount of graphs in one document is limited only by the amount of the free memory;
Lots of design parameters of a coordinate plane (parameters of axes, grid, background, legend);
You can place custom text labels with points on the coordinate plane;
Coefficients on axes;
You can copy graphs as BMP to export them to the Word documents and save graphs as BMP;
