New inequalities involving circular, inverse circular, hyperbolic, inverse hyperbolic and exponential functions

Abstract

In this article, inequalities involving circular, inverse circular, hyperbolic, inverse hyperbolic and exponential functions are established. Obtained results provide new lower and upper bounds for the functions $ x/tanx $, $ x/arcsinx $, $ arctanx/x $, $ tanhx/x $ and $ arcsinhx/x $.
