Gamma and related functions

Gamma and related functions are a family of special functions in mathematics that extend the concept of factorials to non-integer values. ### Gamma Function (Γ) The **Gamma function**, denoted as \( \Gamma(n) \), is defined for all complex numbers except the non-positive integers and can be thought of as a continuous extension of the factorial function. Specifically, for any positive integer \( n \), \[ \Gamma(n) = (n-1)!
