          A well-known {algorithm} for solving equations.  Given an
          equation,
       
          	f x = 0


       
          and an initial approximation, x(0), a better approximation is
          given by:
       
          	x(i+1) = x(i) - f(x(i)) / f'(x(i))
       
          where f'(x) is the first derivative of f, df/dx.
