If the difference between the minimum and. maximum values you set for the pitch of T
or @ 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.
wWSpecifying the Graph Range
When graphing a parametric function, you can specify the maximum and minimum values
to be applied. Use the following format.

Example | To graph the following functions:
x=T7cosT — 2cos 3.5T
y= TsinT -2sin 3,57
