Web2. For each of these, determine whether the described relation R on the set of all people is reflexive, symmetric, antisymmetric, and/or transitive. No need to explain, but feel free to comment if you want. Hint: You can say that (b), (c) and (d) are reflexive, even if the language is awkward. (a) a is taller than b (b) a and b were born on the ... Web27. aug 2024 · There is no example of an irreflexive and antisymmetric relation on X which is neither transitive nor intransitive. However, if R is a relation on as set Y = { a, b, c, d }, then an example exists: [I-A] R = { ( a, b), ( a, c), ( b, c), ( c, d) }

WebExample 6.1.2 Let A = {1, 2, 3, 4, 5, 6} and B = {1, 2, 3, 4}. Define (a, b) ∈ R if and only if (a − b) mod 2 = 0. Then R = {(1, 1), (1, 3), (2, 2), (2, 4), (3, 1), (3, 3), (4, 2), (4, 4), (5, 1), (5, 3), (6, 2), … WebSolved example of reflexive relation on set: 1. A relation R is defined on the set Z (set of all integers) by “aRb if and only if 2a + 3b is divisible by 5”, for all... 2. A relation R is defined … s0a1s0
L-2.2: Reflexive Relation with examples Discrete Mathematics
WebSymmetric relation is defined In set theory as a binary relation R on X if and only if an element a is related to b, then b is also related to a for every a, b in X. Let us consider a mathematical example to understand the meaning of symmetric relations. Define a relation on the set of integers Z as 'a is related to b if and only if ab = ba'. Web3. apr 2024 · 812 views 1 year ago Algebra : Sets and Relations In this video, you will learn how to write an example of a binary relation on a set which is reflexive and symmetric but … WebExample 1: Define a relation R on the set S of symmetric matrices as (A, B) ∈ R if and only if A = B T.Show that R is an equivalence relation. Solution: To show R is an equivalence relation, we need to check the reflexive, symmetric and transitive properties. Reflexive Property - For a symmetric matrix A, we know that A = A T.Therefore, (A, A) ∈ R. ⇒ R is … s0b-3057hd
