Description
|
|
|
•
|
A parametric plot is specified by a list of three items; the first two are real functions of a parameter, the third is the range for the parameter.
|
|
•
|
When used in conjunction with the option coords=polar, parametric plots produces polar plots.
|
|
•
|
Several parametric plots can be plotted on the same graph, by providing a set or a list of parametric plots as the first argument. For more information, see plot.

![plot([x^2, x, x = 0 .. 3*Pi], -8 .. 8, -10 .. 10, coords = polar)](/support/helpjp/helpview.aspx?si=4095/file01017/math107.png)
|
|
>
|
![plot([(t^2-1)/(t^2+1), 2*t/(t^2+1), t = -infinity .. infinity])](/support/helpjp/helpview.aspx?si=4095/file01017/math116.png)

The command to create the plot from the Plotting Guide is

|
![plot([[2*cos(s), sin(s), s = 0 .. 2*Pi], [cos(t), sin(t), t = 0 .. 2*Pi]], color = [blue, yellow])](/support/helpjp/helpview.aspx?si=4095/file01017/math130.png)
