New inequalities between the inverse hyperbolic tangent and the analogue for corresponding functions
In this paper, we present new inequalities which reveal further relationship for both the inverse tangent function arctan ( x ) $\arctan (x)$ and the inverse hyperbolic function arctanh ( x ) $\operatorname{arctanh}(x)$ .

Extended Wang sum and associated products.
The Wang sum involving the exponential sums of Lerch's Zeta functions is extended to the finite sum of the Huwitz-Lerch Zeta function to derive sums and products involving cosine and tangent trigonometric functions.

A new tangent-based probabilistic approach with applications in sports and medical sciences
This paper proposes a new probabilistic method using the tangent function, namely, a new tangent-F family of distributions. It improves the data-fitting ability of its special members by adding a parameter.

The Tangent Stars of a Set and Extensions of Smooth Functions [PDF]
Summary: The \(k\)-th order tangent star, \(\text{Tan}^ k(M,X)\), of a closed subset \(X\) of a \(C^ k\)-manifold \(M\) is defined and studied. The map \((M,X)\mapsto \text{Tan}^ k(M,X)\) is a covariant functor from the category of pairs to the category of stars.

Tangent-Chebyshev rational maps and Redei functions
Recently Lima and Campello de Souza introduced a new class of rational functions over odd-order finite fields, and explained their potential usefulness in cryptography. We show that these new functions are conjugate to the classical family of Redei rational functions, so that the properties of the new functions follow from properties of Redei functions.
