* ''R'' = ''R<sub>0</sub>'' + ''r'' cos ''&theta;'', and
* ''R'' = ''R<sub>0</sub>'' + ''r'' cos ''&theta;'', and
* ''Z'' = ''r'' sin ''&theta;''
* ''Z'' = ''r'' sin ''&theta;''
(''R<sub>0</sub>'' corresponding to the torus axis).
''R<sub>0</sub>'', corresponding to the torus axis, is called the ''major radius'' and ''r'' the ''minor radius''.
''R'' is called the ''major radius'' and ''r'' the ''minor radius''.
''&theta;'' is called the ''poloidal angle''.
''&theta;'' is called the ''poloidal angle''.
