FACTORIAL FUNCTION Meaning and
Definition
-
The factorial function is a mathematical function denoted by the symbol "!". It is typically used to calculate the product of all positive integers from 1 to a given positive integer. For instance, the factorial of 5, represented as "5!", is equal to the product of 5 × 4 × 3 × 2 × 1, which equals 120.
The factorial function can be defined recursively as follows: the factorial of 0, denoted as "0!", is equal to 1, and the factorial of any integer greater than 0, denoted as "n!", is calculated by multiplying that integer with the factorial of its predecessor, (n-1). Mathematically, n! = n × (n-1)!.
The factorial function has various applications in mathematics and statistics, especially in combinatorics and probability theory. It is used to determine the number of permutations or possible arrangements of a given set of objects.
The factorial function is also employed in solving problems related to algorithms and programming. It helps in calculating the number of possible ways to arrange or choose elements in various data structures and algorithms, such as permutations, combinations, and binomial coefficients.
In summary, the factorial function is a mathematical function used to calculate the product of all positive integers from 1 to a given positive integer. It is denoted by the symbol "!" and finds applications in areas like combinatorics, probability theory, and programming.

Etymology of FACTORIAL FUNCTION
The word "factorial" originated from the Latin term "factorialis", which means "relating to a maker or doer". It is derived from the Latin word "factor", meaning "maker" or "doer". In mathematics, the term "factorial" was first introduced by the French mathematician Christian Kramp in his work "Élémens d'arithmétique universelle" in 1808. The concept of factorials has been used in mathematics since ancient times, but it wasn't until Kramp's work that the term "factorial" was formally defined. The word "function" comes from the Latin word "functio", meaning "performance" or "execution". It is derived from the Latin word "fungi", which means "to perform" or "to carry out".
