[pstricks] Using the "psplot"

[Michael M. Dougherty]

Stephane,
It would be helpful if you sent us a list of functions you would like to 
see plotted, and we can send you some code.  It is really quite easy 
once you get started.  If you've never done Reverse Polish Notation it 
takes some getting used to but is also quite easy.  I have given my 
calculus classes notes with many functions plotted in PSTricks (though I 
admitted defeat and needed help from the list for plotting, for 
instance, direction fields).  As Chris pointed out, you don't need to go 
to Mathematica, etc., and besides, the output from Mathematica is not so 
much presentation-quality as with PSTricks properly coded.
