A quick method would be to use "\parametricplot" with the usual pairs
"reversed". For example,

\parametricplot{-1.5708}{1.5708}(57.2958 t mul sin t)

plots arcsin. Note that I've converted the angles (which by default are
measured in degrees in PostScript) to radians (the default for most
mathematicians).

Similarly we can draw arccos also. For arctan, PostScript has the operator
"atan".
