u u u u u To graph parametric functions
You can graph parametric functions that can be expressed in the following format.
f g
(X, Y) = ( (T),
Example To graph the following parametric functions:
x
= 7 cos T – 2 cos 3.5T
Use the following View Window parameters.
Xmin
Xmax = 20
Xscale =
1. In the set up screen, specify "Parm" for Func Type.
2. Specify "Rad" (radians) as the angle unit and then press J.
3. Input the parametric functions.

4. Press w to draw the graph.
u u u u u To graph X = constant
You can graph functions that can be expressed in the format X = constant.
Example To graph X = 3
Use the following View Window parameters.
Xmin
Xmax = 5
Xscale = 1
1. In the set up screen, specify "X=c" for Func Type and then press J.
