Generalized inequalities for ratio functions of trigonometric and hyperbolic functions
Marko Kostić, Yogesh J. Bagul, Christophe Chesneau
Abstract
The main aim of this note, which can be viewed as a certain addendum to the paper \cite{2019}, is to propose several generalized inequalities for the ratio functions of trigonometric and hyperbolic functions. We basically follow the approach obeyed in this paper.
