How accurate does it need to be?

If you need great accuracy, use the mathlib.  If you don't need such
accuracy, use lookup tables.  The code pon Ka-Ping Yee's web site has a
good example.

Look for 'Polyhedra'.  The fixed-point math stuff is shown in fixed.h,
and is *quite* fast, and easier to use than loading mathlib, IMHO.
