Extensions of the natural approach to refinements and generalizations of some trigonometric inequalities
Branko Malesevic, Tatjana Lutovac, Marija Rasajski +1
In this paper we propose a new method for sharpening and refinements of some trigonometric inequalities. We apply these ideas to some inequalities of Wilker-Cusa-Huygens's type.

The natural algorithmic approach of mixed trigonometric-polynomial problems
Tatjana Lutovac, Branko Malesevic, Cristinel Mortici
The aim of this paper is to present a new algorithm for proving mixed trigonometric-polynomial inequalities by reducing to polynomial inequalities. Finally, we show the great appli…
