We approximate a locally unique solution of an equation in Banach space using the Newton–Kantorovich method. Motivated by our earlier works (see references [2–7] in the references list), optimization consideration, and the elegant studies by Cianciaruso with DePascale in (Numer. Funct. Anal. Optim. 27(5–6):529–538, 2006), and Cianciaruso in (Nonlinear Funct. Anal. Appl., 2009, to appear), we provide (by using more precise error estimates on the distances involved): finer error bounds; an at least as precise information on the location of the solution, and a larger convergence domain than in (Numer. Funct. Anal. Optim. 27(5–6):529–538, 2006). Finally, we provide numerical examples where our results can apply to solve equations, but earlier ones can not (see references [8–19]).
