Try Plot[x^3-3x,{x,-3,3}] [You have to supply the x-range for a plot though Mathematica will scale the y-axis appropriately]. I have found the Schaum's Outline Mathematica [available from Wolfram merchandising] very useful for newbies, i.e. me. The Mathematica Book is the bible, the Schaum's book is the tutorial. The bible tells you what is, not how to do it. The tutorial is light on theory but heavy on worked examples and much more useful for a beginner. -- Cheers, PeterV.
