Abstract
The root α of the equation can be determined by using the iterative formula
provided that x
0is a good starting approximation to α and
It is noted here that there are advantages in using the formula
and, where λ is suitably chosen, this formula is equivalent to Aitken's; δ2extrapolation formula. The iterative technique is found to be successful in speeding up the convergence of alternating series and has also been applied to finding zeros of the Riemann Zeta Function.
