The Gamma function is extremely tightly linked to the notion of factorial. While you move on to the Gamma function properties, first let us tell you what the game function operation is.

Factorial operator
Let n be a positive integer. The factorial of n (denoted by n!) is that the product of all integers between (and including) 1 and n:
n! = 1 ⋅ 2 ⋅.......⋅ (n-1) ⋅ n.
For instance
5! = 1 ⋅ 2 ⋅ 3 ⋅ 4 ⋅ 5 = 120.
Factorials are essential in statistics and probability. they need many uses, too many to say here, so allow us to just mention permutations & combinations, binomial coefficients alongside Pascal's triangle, and therefore the binomial probability distribution. If you would like to find out more about factorials, especially their applications, visit our dedicated factorial calculator.
What is essential for us is that the incontrovertible fact that the factorial is merely defined for positive integers. Are there any thanks to extending the factorial to all or any positive numbers? How about all real (or even complex) numbers? We will consider this because of the following interpolation problem:
Can we discover a smooth curve that connects the points (x, y) given by y = x! at the positive integer values for x?
There are several approaches to unravel this problem, and therefore the Gamma function is the hottest one.
Gamma may be a function (denoted by the Greek letter 𝚪) that permits us to increase the notion of factorial well beyond positive integer numbers. Formally, the Gamma function formula is given by an integral (see a subsequent section for more details). Most significantly, the Gamma function and factorials are linked via the relationship:
(n) = (n - 1)!
So it's indeed an answer to the interpolation problem described above. Below you'll see the graph of the Gamma function (n + 1) = n! for all positive numbers (the red dots are the values of the factorial at each integer of x):
Is anyone know that... this function was defined by Swiss mathematician Euler within the half of the 18th century, while the name Gamma and notation 𝚪 was introduced by the French mathematician Adrian-Marie Legendre at the start of the 19th century.
Are you continue to wondering the way to calculate the Gamma function? Well, the simplest answer is: use our Gamma function calculator! Here we briefly describe the way to use it:
Choose the sort of argument you would like our Gamma function calculator to use. By default, we set it to real arguments, but complex numbers are available also.
Enter the argument within the appropriate field(s).
The calculator uses very precise Gamma function approximations to work out the result. It appears just beneath the argument. Enjoy!
If you would like to extend the precision of calculations, attend the advanced mode. By default, this Gamma function calculator uses five sig figs to display the result.
