What is a set of ordered pairs is called?
A set of ordered pairs is a relation. Or Just simply "Coordinates"
The set of the first numbers of the ordered pairs in a relation?
Usually the set of x values.
Why are tuples in a relation not ordered?
A relation is defined as a set of tuples. Mathematically, elements of a set have no order among them; hence, tuples in a relation do not have any particular order. In other words, a relation is not sensitive to the ordering of tuples. Tuple ordering is not part of a relation definition because a relation attempts to represent facts at a logical or abstract level. Many logical orders can be specified on a relation but there is no preference for one logical ordering over another.
What is the domain of a relation?
It is the set on which the relation is defined to the set which is known as the range.
What is The relation is the set of output values for the relation?
A relation doesn't have an "output value", in the sense that a function does. A set of values is either part of the relation, or it isn't.
What is the set of the first numbers of the ordered pairs in a relation called?
they are the first set of paired elements
What is a set of ordered pairs is called an?
A set of ordered pairs is called a relation. In mathematics, a relation defines a relationship between elements of two sets, where each element from the first set is associated with one or more elements in the second set through ordered pairs. For example, if we have a set of ordered pairs like {(1, 2), (3, 4)}, it represents a specific relation between the first elements and the second elements of those pairs.
What is the best definition of a relation in math?
The relation, between two sets of objects, is a mapping which associates elements of the first set to those of the second set.
What is the largest equivalence relation on a set A?
An equivalence relation on a set is one that is transitive, reflexive and symmetric. Given a set A with n elements, the largest equivalence relation is AXA since it has n2 elements. Given any element a of the set, the smallest equivalence relation is (a,a) which has n elements.
What is relation of elements and subsets?
Elements belong to subsets: subsets contain elements (from the parent set).
What makes a relation a function?
A relation is a mapping from one set to another. It is a function if elements of the first set are mapped to only one element from the second set. So, for example, square root is not a function because 9 can be mapped to -3 and 3.
What is the function of relation domain and range in mathematics?
A relation is a mapping from elements of one set, called the domain, to elements of another set, called the range. The function of the three terms: relation, domain and range, is to define the parameters of a mapping which may or may not be a function.
Why duplicate tuples are not allowed in DBMS?
Since relation is a set, and tuples are element of a set, according to set theory, the elements of a set are not ordered.
How do you determine the number of subsets in relation to the universal set?
If the universal set, U, has N elements then it has 2N subsets.
How do you Derive The Number of Transitive relation of a Set 's' having n elements?

What is a set of ordered pairs is called?

How many symmetric relations are there on a set with eight elements?
2^32 because 2^(n*(n+1)/2) is the no of symmetric relation for n elements in a given set
