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".
