The convergence ball and error estimates are given for these methods under hypotheses only on the first Fréchet derivative in contrast to earlier studies such as Adomian (1994) [1], Babajee et al. (2008) [13], Cordero and Torregrosa (2007) [17], Cordero et al. [18], Darvishi and Barati (2007) [19], using hypotheses reaching up to the fourth Fréchet derivative although only the first derivative appears in these methods. This way we expand the applicability of these methods. Numerical examples are also presented in this study. © 2015 Elsevier Inc.Banach spacesNewton-Raphson methodNonlinear equationsAdomianAdomian decompositionConvergence ballError estimatesFirst derivativeLocal ConvergenceNewton's methodsQuadrature rulesIterative methods
