‘or 6 is too great, your graph will be too rough. If the difference is too small, drawing of
the graph will take a very long time.
Specifying the Graph Range
When graphing a polar coordinate function, you can specify the maximum and minimum
values to be applied. Use the following. format.

8-4 Parametric Graphs
To draw parametric graphs, first change to the PRM Mode. Do not try to use the BASE,
EQUA, DYNA or TABLE Mode for graphing. The functions that can be graphed in the
PRM Mode are those that fit the following format:
(x, »)=(A(T), 87)
