Web2.3 Gamma Function. The Gamma function Γ(x) is a function of a real variable x that can be either positive or negative. For x positive, the function is defined to be the numerical outcome of evaluating a definite integral, … WebMay 5, 2013 · Euler discovered the gamma function, Γ(x), when he extended the domain of the factorial function.Thus Γ(x) is a meromorphic function equal to (x − 1)! when x is a positive integer.The gamma function has several representations, but the two most important, found by Euler, represent it as an infinite integral and as a limit of a finite product.
