Generalized bounds for hyperbolic sine and hyperbolic cosine functions

R. M. Dhaigude, Y. J. Bagul, V. M. Raut

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.
