Derivation of a new semi-imlicit Runge-Kutta method of contra-harmonic mean with forward-backward technique

Journal of Interdisciplinary Mathematics
In this article, the new method that solves Initial Value Problems IVPs is presented, where we derived our new method by using the Contra Harmonic CH mean instead of the classic arithmetic mean, more than the Forward Backward FB) technique to calculate both sides of the predictor (Forward) part and corrector (Backward) part of our semi-implicit method.

Contra-Harmonic Mean Derivative-Based Open Newton-Cotes Quadrature Rules

SINDH UNIVERSITY RESEARCH JOURNAL -SCIENCE SERIES
A novel family of open Newton-Cotes formulas is created to assess definite integrals. The new family is formed by taking the Contra-Harmonic Mean of the function's first-order derivatives within the interval [a,b]. In comparison to the classical open Newton-Cotes quadrature rules, the proposed derivative-based quadrature rules improve accuracy by two ...

A Numerical Approach for Solving Fuzzy Differential Equation Using Enhanced Euler’s Methods Based on Contra Harmonic Mean and Centroidal Mean

Communications on Applied Nonlinear Analysis
Objectives: Fuzzy differential equations (FDEs) are crucial for modeling dynamic systems in science, economics, and engineering due to their unpredictable nature and the need for numerical methods for precise solutions. The objective of this work is to develop improved Euler's techniques for numerically solving fuzzy differential equations (FDEs) in ...
