Coordinate Systems
3D Grapher provides for three systems of coordinates: Cartesian, cylindrical, and spherical.
Cartesian
The variables X, Y, and Z correspond to the right-handed Cartesian (or rectangular) coordinate system.
Cylindrical
In the three-dimensional graphs, the variables a, R, and Z correspond to the cylindrical coordinate system.
In the two-dimensional graphs, the variables a and R correspond to the polar coordinate system.
Spherical
The variables a, b, and R correspond to the spherical coordinate system.
