The Gamma Series is a sequence of mathematical functions that extend the concept of factorials to non-integer values. It is denoted as Γ(n), where n can be any real or complex number. The Gamma function is defined for positive numbers and is calculated using an integral formula, making it useful in various fields such as statistics, physics, and engineering. One of the key properties of the Gamma function is that for any positive integer n, Γ(n) equals (n-1)!. This relationship allows the Gamma function to bridge the gap between discrete and continuous mathematics, providing a powerful tool for solving problems involving probabilities and complex calculations.
