The main objective of this paper is to establish several new lower and upper bounds for the functions $\sinh x/x$ and $\cosh x$. Following the simple approach, our results give refinements and generalizations of some known inequalities involving these functions.
This paper is dedicated to Professor Edward Neuman on his 77th birthday.
