Steffensen-type methods with memory were originally designed to solve nonlinear equations without the use of additional functional evaluations per computing step. In this paper, a variant of Steffensen’s method is proposed which is derivative-free

In this paper, we present new one- and two-steps iterative methods for solving nonlinear equation f(x)=0. It is proved here that the iterative methods converge of order three and six respectively. Several numerical examples are given to illustrate th

In this paper, three types of weighted residual methods (Collocation, Subdomain, and Galerkin methods) are presented for finding an approximate (sometimes exact) solution of the system of non-linear Volterra integral equations of the second kind (VIE

Abstract In this paper, we consider the construction of the sextic splines function which interpolating the lacunary data. Also, under suitable conditions, we show that the existence and uniqueness of the solution. The convergence analysis of this sp

This study determines the numerical solution of linear mixedVolterra-Fredholm integral equations of the second kind using the linear splinefunction. The proposed method is based on using the unknown function’s linearspline function at an arbitrary

High speed liquid jet forms when a bubble collapses near a solid boundary. The formation of the jet has both advantages and disadvantages as it causes erosion and damage in the nearby turbomachinery and can be beneficially applied in surface cleaning

Data completion known as Cauchy problem is one most investigated inverse problems. In this work we consider a Cauchy problem associated with Helmholtz equation. Our concerned is the convergence of the well-known alternating iterative method [25]. Our
