Inequalities Involving Hyperbolic Functions and Trigonometric Functions


Edward Neuman




Inequalities involving hyperbolic functions and trigonometric functions are established. Most of the established inequalities can be regarded as the companion inequalities to those obtained by Lazarevi\'c, Adamovi\'c and Mitrinovi\'c and Cusa and Huygens The established results are obtained with the aid of the Schwab-Borchardt mean.
