Consider the integral form of the Gamma function, Γ(x) = ∫∞ 0e − ttx − 1dt taking the derivative with respect to x yields Γ ′ (x) = ∫∞ 0e − ttx − 1ln(t)dt. Setting x = 1 leads to Γ ′ (1) = ∫∞ 0e − tln(t)dt. This is one of the many definitions of the Euler-Mascheroni constant. Hence, Γ ′ (1) = − γ ...
