Abstract :
In this paper, we establish new sharpened versions of Mitrinović-Adamović and Lazarević s inequalities. Further, we provide an application of our results to the improvements of Wilker s inequality for trigonometric and hyperbolic functions. We show that the coefficient assigned to each of these sharpened inequalities is best possible.
