Sharp inequalities for bounding Seiffert mean in terms of the arithmetic, centroidal, and contra-harmonic means

Mathematica Slovaca, 2016
AbstractIn the paper, the authors find two sharp and double inequalities for bounding the second Seiffert mean either by a one-parameter family of means derived from the centroidal mean or by a convex combination of the arithmetic and contra-harmonic means.

A new fourth order runge-kutta formula based on the contra-harmonic (C₀M) mean

International Journal of Computer Mathematics, 1995
In this paper new Runge-Kutta formulae of orders 3 and 4 based on the contra harmonic mean are derived. Numerical evidence confirming the accuracy of the new method and comparison with alternative Runge-Kutta formula based on arithmetic, geometric and harmonic means are also presented.

Schur m-Power Convexity of Generalized Invariant Contra Harmonic Means

Journal of Inequalities and Mathematical Analysis
In this paper, we investigate the Schur m-power convexity of the generalized invariant contra harmonic means, then some related results are generalized. As applications, some new inequalities involving Gini mean, arithmetic mean, geometric mean and harmonic mean are established.

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 ...
