Using the weierstrass definition for $\gamma (x)$ and $\gamma\big (x \frac12\big)$, how can i prove the duplication formula? this is problem $10.7.3$ in the book irresistible integrals, by boros and moll.

Gamma Function From Wolfram Mathworld Gamma function satisfies the following identity for all complex z: 22z−1 1 Γ (2z) = √ Γ (z)Γ z , π 2 referred to as legendre duplication formula. we start from the integral expression of beta function of equal arguments: 1 z. If a positive function f ⁡ (x) on (0, ∞) satisfies f ⁡ (x 1) = x ⁢ f ⁡ (x), f ⁡ (1) = 1, and ln ⁡ f ⁡ (x) is convex (see § 1.4 (viii)), then f ⁡ (x) = Γ ⁡ (x). The duplication formula relates the gamma function at a given value to the gamma function at half that value and other values. Gamma functions of argument 2z can be expressed in terms of gamma functions of smaller arguments. from the definition of the beta function, b (m,n)= (gamma (m)gamma (n)) (gamma (m n))=int 0^1u^ (m 1) (1 u)^ (n 1)du.

Not the question you're searching for? duplication formula, gamma function. the duplication formula is a special identity for the gamma function, which is useful in various areas of mathematics, including complex analysis and number theory. the formula is given by: Γ(z)Γ(z 21) = 21−2z πΓ(2z). Some sources report legendre's duplication formula in the form: some sources refer to legendre's duplication formula as just the duplication formula. this entry was named for adrien marie legendre. Establish the symmetry formula for the gamma function. speci cally, for 0 < s < 1, the long computation just shown also gives, with a = s and b = 1 s, no. For example, the multiplication theorem for the gamma function follows from the chowla–selberg formula, which follows from the theory of complex multiplication.
