Derivative of a gamma function
Web2 Let Γ ( x) = ∫ 0 ∞ t z − 1 e − t d t. I know that the first derivative is positive, since Γ ( x) is increasing when x > 0, but I don't know how to show that the second derivative is positive without calculating it, something which we have not yet learned to do.

WebAug 1, 2024 · Solution 1. 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 ...
