## Abstract

Let \(X_{1},X_{2}\) be two Banach spaces and \(f:X_{1}\rightarrow X_{2}\) a nonlinear equation. We study the chord method for solving the equation \(f\left( x\right) =0\). Assuming the first order divided differences of \(f\) satisfy a Holder type condition, we obtain sufficient convergence conditions and error estimations at each step.
