What made you think PSTricks could understand this kind of written  
maths? AFAIR you need to enter PostScript commands, for example:

	x 3 exp 400 div x dup mul 3 mul 20 div sub x 3 mul add 22 sub

i.e. (x^3)/400 - x*x*3/20 + x*3 - 22


OTOH, it would be nice if PSTricks would understand non-PostScript  
maths ...

When in doubt, use brute force.
