What is the Gamma Function Calculator & How does it work?
The Gamma function, denoted by Ξ“(z), is a generalization of the factorial function to complex and real numbers. For positive integers, Ξ“(n) = (n-1)!. It extends the concept of factorials to non-integer values, playing a crucial role in various fields such as statistics, physics, and engineering.
Ξ“(z) = int_0^infty t^{z-1} e^{-t} dt
z = positive real number
The Gamma function is defined for all complex numbers except the non-positive integers. It satisfies the property Ξ“(z+1) = zΞ“(z), which is analogous to the factorial’s n! = n(n-1)!.
