In this article, we prove that the double inequality α P (a, b)+ 1 (1− α) Q (a, b)< M (a, b)< β P
(a, b)+(1− β) Q (a, b) holds for any a, b> 0 with a≠ b if and only if α≥ 1/2 and β≤[π (2 log …

In this paper, we establish three families of trigonometric functions with two parameters and
prove their monotonicity and bivariate log-convexity. Based on them, three two-parameter …

We prove that p= 1 and q= 2 are the best possible parameters in the interval (0,∞) such that
the double inequality (ep/(x+ 1)− e− p/x)/2p< ψ′(x+ 1)<(eq/(x+ 1)− e− q/x)/2q holds for x> 0 …

Inequalities involving trigonometric and hyperbolic functions are established. Obtained
results provide refinements or generalizations of inequalities proved by Adamovic and …

In the paper, the authors establish a general inequality for the hyperbolic functions, extend
the newly-established inequality to trigonometric functions, obtain some new inequalities …
