Witryna23 lut 2016 · $\begingroup$ @YulInn: The most natural and elemenary definition of the natural logarithm---or its inverse, the exponential---is via calculus, or at least as a limit. The handicap of not using calculus is artificial; so it is not surprising that the above proof is circuitous. If only rational numbers featured as base and index, then limits would … Witryna1 Answer. Sorted by: 3. As mentioned in this answer , d d x log ( Γ ( x)) = Γ ′ ( x) Γ ( x) = − γ + ∑ k = 1 ∞ ( 1 k − 1 k + x − 1) where γ is the Euler-Mascheroni Constant. It is also mentioned there, that when x is a positive integer, ∑ k = 1 ∞ ( 1 k − 1 k + x − 1) = ∑ k = 1 x − 1 1 k = H x − 1. where H n is the ...
