• Polar coordinate (r=)
• Parametric (Parm)

* The number table is generated only for the
function type specified on the relation list
(Table Func). You cannot generate a number table
for a mixture of different function types.
The function type specified in the GRAPH mode is
not one of these three, entering the TABLE mode
causes the function type to change to rectangular
coordinate (Y=).
