WebTo simplify the terminology, we often say pair for or-dered pair,withtheunderstandingthatpairsarealways ordered (otherwise, we should say set). Of course, given three sets, A,B,C,wecanform (A × B) × C and we call its elements (ordered) triples (or triplets). WebDefinition: Relation A relation from a set A to a set B is a subset of A × B. Hence, a relation R consists of ordered pairs (a, b), where a ∈ A and b ∈ B. If (a, b) ∈ R, we say that is related to , and we also write aRb. Remark We can also replace R by a symbol, especially when one is readily available.

At... WebAn n -tuple, with n > 0, can be defined as an ordered pair of its first entry and an (n − 1) -tuple (which contains the remaining entries when n > 1) : This definition can be applied recursively to the (n − 1) -tuple: Thus, for example: A variant of this definition starts "peeling off" elements from the other end: The 0-tuple is the empty set .

The second example is not a function, because it... WebOrdered Pairs . An ordered pair is a pair of numbers in a specific order. For example, (1, 2) and (- 4, 12) are ordered pairs. The order of the two numbers is important: (1, 2) is not equivalent to (2, 1)-- (1, 2)≠(2, 1). Using Ordered …
WebApr 9, 2024 · For example: Consider two ordered pairs (a, b) and (c, d). They are equal if a = c and b = d, i.e., (a, b) = (c, d).

Webof x and y, and x _y denotes the least upper bound for a pair of elements x and y, frequently called the join of x and y. As perhaps an explanation for the use of this notation, consider the following example, the proof of which is left as an exercise. Example 5.

WebJul 15, 2024 · The usual definition of the ordered pair of a and b is. (a,b) = { {a}, {a,b} }. It has the property (exercise) (a,b) = (u,v) iff a = u, b = v. That property is the essence of ordered pairs. As you see, it is definable for any two things regardless of their nature even if it includes an order.
