9.9.2 Methods Using Inverse Interpolation
The interpolatory methods referred to above are hard to implement if the degree of 
is greater than 2 or 3. In many ways inverse interpolation is easier to implement, and several authors describe methods based on this process. For example consider Traub (1962): let 
have an inverse function 
, then he shows that
(9.735)
where as usual ,
(9.736)
(9.737)
and where for the inner sum is taken over all such ...
