WebInductive Step: Let k be a positive integer. Assume that whenever max (x, y) = k and x and y are positive integers, then x = y. Now let max (x, y) = k + 1, where x and y are positive integers. Then max (x − 1, y − 1) = k, so by the inductive hypothesis, x − 1 = y − 1. It follows that x = y, completing the inductive step. discrete math.

Let R be the relation on … WebThe given relation R in set R of real numbers is defined as R = {(a, b): a ≤ b}. (a, a) ∈ R, since, for all values of a, a ∈ R, a ≤ a. Hence, R is reflexive. Let, (a, b) ∈ R, therefore a ≤ b. Then (b, a) ∉ R since b ≥ a. Hence, R is not symmetric. Let, (a, b), (b, c) ∈ R, thus a ≤ b and b ≤ c. So, a ≤ c implies that (a ...
WebA partial order is if R is reflexive on A, antisymmetric and transitive. One must prove these properties true. My question for this problem is trying to comprehend why this problem is antisymmetric and why it is transitive. ( i) R is reflexive as we say x = a and y = b. Thus we can conclude that that x ≤ x, y ≤ y. ( x, y) R ( x, y). If b ...

Web13 mei 2024 · Hence, R is reflective. (ii) Transitivity. Consider a, b and c ∈ S where (a, b) and (b, c) ∈ S. We get (a, b) ∈ R => a ≤ b and (b, c) ∈ R => b ≤ c. Based on the above equation we get (a, c) ∈ R => a ≤ c. Hence, R is transitive. (iii) Non symmetry. We know that (5, 6) ∈ R => 5 ≤ 6. In the same way (6, 5) ∈ R => 6 ≰ 5 ...
