We study the properties of the logarithm of the derivative operator and show that its action on a constant is not zero, but yields the sum of the logarithmic function and the Euler-Mascheroni constant. We discuss more general aspects concerning the logarithm of an operator for the study of ...

To differentiate the natural logarithm of a function g(x), namely, ln g(x), use the fol- lowing formula. Derivative of ln g(x) The formula for finding the derivative of the composite function f(x) ϭ ln g(x), where g is a differentiable function, is d dx ln g(x) ؍ d ...
Faulhuber and Steinerberger conjectured that the logarithmic derivative of ϑ4 has the property that y2ϑ4′(y)/ϑ4(y) is strictly decreasing and strictly convex. In this small note, we prove this conjecture. Résumé Faulhuber et Steinerberger ont conjecturé que la dérivée logarithmiq...
摘要: In this paper a new q -derivative is proposed and its properties are discussed. We define q -addition and study its axiomatic properties. The q -exponents and q -logarithmic function are introduced and their algebraic structure discussed....
