Some new bounds for ratio functions of trigonometric and hyperbolic functions
Résumé
This paper is devoted to obtain sharp exponential and polynomial upper bounds for the ratio functions cosh x/cos x and sinh x/sin x. The proofs are based on the use of a refinement of a special case of the Bernoulli inequality and infinite products.
