For the following examples, we will define two sets, A and B. A[B = fx jx 2A_x 2Bg Intersection The intersection of the sets A and B, denoted by A \B, is the set containing those elements in both A … 3�+\! Hence, A ∪ B = { x | x ∈ A OR x ∈ B }.

Set Operations Operations between sets allow us to examine and manipulate the contents of sets in ways similar to logical and Boolean operations. Let fuzzy sets A and B be described by their membership functions μ A (x) and μ B (x).The three fuzzy set operations are defined below. This set operator is used to combine the outputs of two or more queries into a single set of rows and columns having different records. Methods. 0000001635 00000 n

There are a large number of set operations, including union (|), intersection (&), difference (-), symmetric difference (^). The difference between sets is denoted by ‘A – B’, which is the set containing elements that are in A but not in B.

Each object is called anelement. ex) U={integers from 1 to 10} A={3,6,9}, A={1,2,4,5,7,8,10} which are all elements from the universal set that are not found in A. There is a set of rules that reduces the number of parenthesis required. The union of sets A and B (denoted by A ∪ B) is the set of elements that are in A, in B, or in both A and B. hޜ�wTT��Ͻwz��0�z�.0��. 83 0 obj
