To graph parametric functions
You can graph parametric functions that can be expressed in the following format.
(X, Y) = ( f (T), g (T))
Example To graph the following parametric functions:
x = 7 cos T – 2 cos 3.5T
y = 7 sin T – 2 sin 3.5T
Use the following View Window parameters.
Xmin = –20 Ymin = –12
Xmax = 20 Ymax = 12
Xscale = 5 Yscale = 5
