Abstract:In a recent paper, Adamchik 1] expressed in a closed-form symbolic derivatives of four functions belonging to the class of functions whose derivatives are polynomials in terms of the same functions. In this sequel, simple closed-form higher derivative formulae which involve the Carlitz-Scoville higher order tangent and secant numbers are derived for eight trigonometric and hyperbolic functions.
Keywords:Closed-form formula  Tangent numbers of order k  Secant numbers of order k  Higher (generalized) tangent numbers  Higher (generalized) secant numbers  Derivative formula  Derivative polynomials
