关于三角函数与双曲函数的经典不等式

On classical inequalities of trigonometric and hyperbolic functions

Barkat Ali Bhayo, Jozsef Sandor

摘要:

本文是作者最近撰写的六篇研究论文的集合。本文改进了三角函数和双曲函数的不等式,如Adamovic-Mitrinovic不等式、Cusa-Huygens不等式、Lazarevic不等式、Huygens不等式、Jordan不等式、Carlson不等式、Wilker不等式、Redheffer不等式、Wilker-Anglesio不等式、Becker-Stark不等式、Kober不等式、Shafer不等式和Shafer-Fink不等式。建立了三角函数与双曲函数之间的关系。本文通过研究Jordan不等式,建立了经典β函数的精确上、下界.

英文摘要:

This article is the collection of the six research papers, recently written by the authors. In these papers authors refine the inequalities of trigonometric and hyperbolic functions such as Adamovic-Mitrinovic inequality, Cusa-Huygens inequality, Lazarevic inequality, Huygens inequality, Jordan's inequality, Carlson's inequality, Wilker's inequality, Redheffer's inequality, Wilker-Anglesio inequality, Becker-Stark inequality, Kober's inequality, Shafer's inequality and Shafer-Fink's inequality. The relation between trigonometric and hyperbolic functions has been built too. In the last paper, the sharp upper and lower bounds for the classical beta function has been established by studying the Jordan's inequality.
