Describe the equivalence classes
WebFormally, given a set S and an equivalence relation ~ on S, the equivalence class of an element a in S is the set. of elements which are equivalent to a. It may be proven from the defining properties of "equivalence relations" that the equivalence classes form a partition of S. This partition – the set of equivalence classes – is sometimes ...

WebSee Answer. Question: For each relation, determine whether the relation is (i) reflexive, (ii) symmetric, (iii) transitive, (iv) an equivalence relation. If the relation is an equivalence relation, describe the distinct equivalence classes. The relation R on Z defined by: For all m,n € Z, mRn if and only if m^2 — n^2 is even. WebJul 7, 2024 · Because of the common bond between the elements in an equivalence class [a], all these elements can be represented by any member within the equivalence class. This is the spirit behind the next theorem. Theorem 7.3.1. If ∼ is an equivalence relation on A, then a ∼ b ⇔ [a] = [b].
WebDe nition 4. Let ˘be an equivalence relation on X. The set [x] ˘as de ned in the proof of Theorem 1 is called the equivalence class, or simply class of x under ˘. We write X= ˘= f[x] ˘jx 2Xg. Example 6. If we consider the equivalence relation as de ned in Example 5, we have two equiva-lence classes: odds and evens. WebAnswer (1 of 3): First, we note that (a,a) \in ~, since 3a + 4a = 7a, which is divisible by 7 since a \in \mathbb{Z}. So, ~ is reflexive. Now, assume (a,b) \in ~. Then 3a + 4b is divisible by 7, so we can write 3a + 4b = 7n, for n \in \mathbb{Z}. Now, note that (3a + …
Web1st step. Solution: The relation R on the set of integers ( Z) is defined as follows: x R y if and only if 3 x − 5 y is even. To describe the equivalence classes of R, we need to find sets of integers that are related to each other under this relation. In other words, we need to identify sets of integers that produce even values when plugged ... WebProof. Suppose R is an equivalence relation on A and S is the set of equivalence classes of R. If S is an equivalence class, then S = [a], for some a ∈ A; hence, S is nonempty, …
