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.

WebReflexive: The relation R is not reflexive since, for example, (2,2) is not in R. Irreflexive: The relation R is not irreflexive, since for example (1,1) and (3,3) are in R. Symmetric: The relation R is not symmetric, since for example (2,1) is in R but (1,2) is not. WebAug 16, 2024 · Since r is a relation from A into the same set A (the B of the definition), we have a 1 = 2, a 2 = 5, and a 3 = 6, while b 1 = 2, b 2 = 5, and b 3 = 6. Next, since 2 r 2, we have R 11 = 1 2 r 5, we have R 12 = 1 5 r 6, we have R 23 = 1 6 r 6, we have R 33 = 1 All other entries of R are zero, so R = ( 1 1 0 0 0 1 0 0 1)
