The natural algorithmic approach of mixed trigonometric-polynomial problems. [PDF]
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 applicability of this algorithm and as examples, we use it to analyze some new ...

On the generalized Becker-Stark type inequalities
In this paper, we establish several generalized Becker-Stark type inequalities for the tangent function. We present unified proofs of many inequalities in the existing literature. Graphical illustrations of some obtained results are also presented.

On logarithm of circular and hyperbolic functions and bounds for exp(±x2)
We show that certain known or new inequalities for the logarithm of circular hyperbolic functions imply bounds for exp(±x2) proved in [1].

Refinements of Some Classical Inequalities Involving Sinc and Hyperbolic Sinc Functions
Several bounds of trigonometric-exponential and hyperbolic-exponential type for sinc and hyperbolic sinc functions are presented. In an attempt to generalize the results, some known inequalities are sharpened and extended.

Geometric convexity of the generalized sine and the generalized hyperbolic sine [PDF]
In the paper, the authors prove that the generalized sine function $\sin_{p,q}(x)$ and the generalized hyperbolic sine function $\sinh_{p,q}(x)$ are geometrically concave and geometrically convex, respectively.
