This template sets the coordinate attribute for the coordinate systems known to the Vector Calculus package. The commonly used coordinate systems, both two- and three-dimensional, are Cartesian, polar, cylindrical, and spherical. The other 2-D and 3-D systems are grouped separately. Select a group of systems by clicking the appropriate radio button. This will give access to the drop-down listing of the systems in that group. After making that selection, you can specify the names of the coordinate variables in the system. Finally, click the Set System button to set the system as the default for the VectorCalculus packages.
