The equation f (x) 0 can be rearranged in the form of a fixed point equation
g(x) f (x) x x. The solution(s) to such type of equation is(are) computed
iteratively through some iterative procedure. The Newton-Raphson ((N-R) method
is one of the most popularly used iterative methods for solving such nonlinear
equations. If n1 x
represents
the (n+1)th iterate of the N-R method, then we have

The N-R method and other iterative methods are extensively studied by various
authors and a number of variants of them appeared in the literature, see for
instance, [1-3], [7-8], [10-15] and references therein. In this paper, we propose a
new iterative algorithm from the N-R method and study the error estimate and rate
of convergence of it.
