The interesting thing about this integral is that it also works for $n$ that is not a natural number (and the result is a nice smooth function of $n$). The factorial of one half ($0.5$) is thus defined as $$ (1/2)! = ∫_0^∞ x^{1/2}e^{-x}\,dx $$ We will show that:

In mathematics, the factorial of a non-negative integer , denoted by , is the product of all positive integers less than or equal to . The factorial of also equals the product of with the next smaller factorial: For example, The value of 0! is 1, according to the convention for an empty product. [1]
The factorial of n is denoted by n! and calculated by multiplying the integer numbers from 1 to n. The formula for n factorial is n! = n × (n - 1)!. Example: If 8! is 40,320 then what is 9!? Solution: 9! = 9 × 8! = 9 × 40,320 = 362,880
The factorial function (symbol: !) says to multiply all whole numbers from our chosen number down to 1. Examples: 4! = 4 × 3 × 2 × 1 = 24. 7! = 7 × 6 × 5 × 4 × 3 × 2 × 1 = 5040. 1! = 1. We usually say (for example) 4! as "4 factorial", but some people say "4 shriek" or "4 bang".
3 Αυγ 2022 · The factorial of a number is the multiplication of all the numbers between 1 and the number itself. It is written like this: n!. So the factorial of 2 is 2! (= 1 × 2). To calculate a factorial you need to know two things: 0! = 1. n! = (n - 1)! × n.
The factorial function is defined for all positive integers, along with 0. What value should 0! have? It's the product of all integers greater than or equal to 1 and less than or equal to 0. But there are no such integers. Therefore, we define 0! to equal the identity for multiplication, which is 1.
12 Ιαν 2024 · It is easy to calculate and multiply two factorials using a scientific calculator’s ! function. You can also multiply factorials by hand. The easiest way to do it is to calculate each factorial individually, and then multiply their products together.
