Generalized bounds for sine and cosine functions
Résumé
In this paper, we propose several new lower and upper bounds for the functions sin x/x and cos x. In iparticular, we refine by generalizing some known inequalities involving these functions. To attain this aim, monotonicity rules and ratio of consecutive even indexed Bernoulli numbers play an important role.
