Remember that any kind of calculation can be speeded up and made more
accurate by using table lookup.  Thus instead of using cumbersome and
slow calculations to do sin just do table lookup.  (You'd be surprized
how many applications could use a fast sin function).  The more memory
the more functions can be economically made into tables.  Thus one can
justify larger memory for any user who has critical functions that are slower
than a few memory references.
