A Family of Two-Variable Derivative Polynomials for Tangent and Secant
Keywords: Derivative polynomials, Eulerian polynomials, Tangent function, Secant function
In this paper we introduce a family of two-variable derivative polynomials for tangent and secant. Generating functions for the coefficients of this family of polynomials are studied. In particular, we establish a connection between these generating functions and Eulerian polynomials.
