Monotonous two-parameter functions for asymptoticly approximating the inequalities involving the inverse tangent functions

XD Chen, C Qian, P Zhu, X Pan - Revista de la Real Academia de …, 2022 - Springer
In this paper, we present a family of two-parameter functions, which are used to asymptoticly
approximating the inverse tangent function. It can recover some of previous results, and it …
