WebFeb 27, 2024 · Definition: Gamma Function The Gamma function is defined by the integral formula (14.2.1) Γ ( z) = ∫ 0 ∞ t z − 1 e − t d t The integral converges absolutely for Re ( z) > 0. Properties Γ ( z) is defined and analytic in the region Re ( z) > 0. Γ ( n + 1) = n!, for integer n ≥ 0. Γ ( z + 1) = z Γ ( z) (function equation) WebLet's expand the Beta in terms of Gamma-functions: B ( a, b) = Γ ( a) Γ ( b) Γ ( a + b), so B ( 1 − x, 1 + x) = Γ ( 1 − x) Γ ( 1 + x) / Γ ( 2). Γ ( 2) = 1. Meanwhile, Γ ( 1 − x) Γ ( 1 + x) = x Γ ( x) Γ ( 1 − x) = x π sin π x using the reflection formula, so d d x B ( 1 − x, 1 + x) = π csc π x − π 2 x csc π x cot π x = π ( 1 − π x cot π x) csc π x.
