I'm breaking my commitment to not answer questions, but I don't think 
anyone will get mad this time ;-)

The way I have done this is by using Algebra.  Solve for 3.13 and -3.13 
and plot the function between those points.  (I.e. -1.56 to 1.56, or a 
hair less than -pi/2 to pi/2.)

PStricks is really cool, but it is a real bear to get started with :-(
