What is a Relation?
A Relation in mathematics are used to describe a connection between the elements of two sets. They help to map the elements of one set (known as the domain) to elements of another set (called the range) such that the resulting ordered pairs are of the form (input, output). It is is a subset of the cartesian product of two sets. Suppose there are two sets given by X and Y. Let x ∈ X (x is an element of set X) and y ∈ Y. Then the cartesian product of X and Y, represented as X × Y, is given by the collection of all possible ordered pairs (x, y). In other words, a relation says that every input will produce one or more outputs.
How to Calculate Number of Relations from Set A to Set B?
Number of Relations from Set A to Set B calculator uses Number of Relations from A to B = 2^(Number of Elements in Set A*Number of Elements in Set B) to calculate the Number of Relations from A to B, Number of Relations from Set A to Set B formula is defined as the number of ordered pairs (a, b) where a is an element of A and b is an element of B such that a ∈ A and b ∈ B, and all of which are a subset of A × B. Number of Relations from A to B is denoted by NRelations(A-B) symbol.
How to calculate Number of Relations from Set A to Set B using this online calculator? To use this online calculator for Number of Relations from Set A to Set B, enter Number of Elements in Set A (n(A)) & Number of Elements in Set B (n(B)) and hit the calculate button. Here is how the Number of Relations from Set A to Set B calculation can be explained with given input values -> 4096 = 2^(3*4).
