The Gamma Function, denoted as Γ(n), is a mathematical function that extends the concept of factorial to real and complex numbers. It is defined as Γ(n) = (n-1)! for all positive integers n.
The Gamma Function is primarily used to calculate the values of integrals and series that involve factorials. It also has applications in probability theory, statistics, and other areas of mathematics and science.
The Gamma Function is an extension of the factorial function to real and complex numbers. For positive integers, n, Γ(n) is equivalent to (n-1)!. However, the Gamma Function can be used for non-integer values of n as well.
There are several methods for calculating the Gamma Function, including using numerical approximations, series expansions, and recurrence relations. The most common method is to use the Lanczos approximation, which is a fast and accurate algorithm for calculating Γ(n) for any real or complex number n.
The Gamma Function has several important properties, including the fact that it is a continuous function, it is strictly increasing on the interval (0,∞), and it satisfies the recurrence relation Γ(n+1) = nΓ(n) for all positive integers n. It also has connections to other mathematical functions such as the Beta Function and the digamma function.
