ParametricPlot
ParametricPlot[{fx,fy},{u,umin,umax}] generates a parametric plot of a curve with x and y coordinates fx and fy as a function of u.
ParametricPlot[{{fx,fy},{gx,gy},…},{u,umin,umax}] plots several parametric curves.
ParametricPlot[{fx,fy},{u,umin,umax},{v,vmin,vmax}] plots a parametric region.
ParametricPlot[{{fx,fy},{gx,gy},…},{u,umin,umax},{v,vmin,vmax}] plots several parametric regions.
ParametricPlot[{…,w[{fx,fy}],…},…] plots the curve {fx,fy} with features defined by the symbolic wrapper w.
ParametricPlot[…,{u,v}∈reg] takes parameters {u,v} to be in the geometric region reg.
