A parametric plot displays the image traced by parametric equations as their parameter varies over a specified interval. A plane parametric plot has the form

while three component functions define a space curve. Unlike the graph of a single-valued function 
, a parametric plot may double back,
have vertical tangents, or pass through the same
point for different parameter values.
The cycloid parametrized by

is illustrated above.
The Wolfram Language function ParametricPlot[

, 
t,
tmin, tmax
]
plots a plane parametrized curve, and its three-component form plots a space
curve.
