. Stirling's approximation is asymptotically equal to the factorial function for large values of n. It is possible to find a general formula for factorials using tools such as integrals and limits from calculus. A good solution to this is the gamma function. There are infinitely many continuous...
gamma functionpolygamma functionsBernoulli polynomialsA new view on classical asymptotic expansions of the logarithm of gamma function is given. Then general formulae for the asymptotic expansions of the logarithm of gamma function and the Wallis power function through polygamma functions are derived and ...
Gamma functions of argument can be expressed using a triplication formula (51) The general result is the Gauss multiplication formula (52) The gamma function is also related to the Riemann zeta function by (53) For integer , 2, ..., the first few values of are 1, 1, 2, 6,...
Today we’re going to discuss one of the non-elementary functions called gamma function and consider some of its properties. Gamma function is of great importance, it’s widely applied in math (in particular, when integrating certain types of expression gamma function helps greatly, we’ll see ...
Recursive formulaGiven the above definition, it is straightforward to prove that the Gamma function satisfies the following recursion: ProofRelation to the factorial functionWhen the argument of the Gamma function is a natural number then its value is equal to the factorial of : ...

The gamma function can be defined as a definite integral for (Euler's integral form) (3) (4) or (5) The complete gamma function can be generalized to the upper incomplete gamma function and lower incomplete gamma function . Min Max ...
formula for the factorials. The so-called Gamma function is defined in Rudin [9] as follows: Definition 1.1. For 0 < x < ∞, Γ(x) :=∞ 0 t x−1 e −t dt. (1.2) But what does definition 1.1 mean? We are used to integrating over a closed interval [a, b], not...
