5. On the set of integers Z define the following relation: "aRb if and only if a - b is a multiple of 7." (1) Prove that R is an equivalence relation. 16 Marks] How many elements are there in the quotient set of 2 with respect to the equivalence relation R? Give reasons. |4 Marks
The assertion, as given in the source: (Theorem 3.4.8 of Johnsonbaugh's text.) Let R be an equivalence relation on a set X. For each a in X, define [a] as (xeX | xRaj. Then the following set is a partition of X: S={[a] l a eX). Logical structure of the assertion: Proof framework, based on this logical structure: Previous resulis needed (give one to three previous resulis that are most important for this prooj): Interesting or unexpected tricks, or summary:...
10. Verify that the relations given below are quasiorders. List the elements of each equivalence class of the induced equivalence relation, and draw the Hasse (a) On the set (1,2,..., 303, define mn if and only if the sum of the digits (b) On the set (1.2,3,4,11, 12, 13,14,21,22,23,24), define mn if and only diagram for the induced partial order on the equivalence classes of m is less than or equal to the sum of the digits of n. if...

Question 8 Let R be relation on a set A. 1. When is R said to be an equivalence relation? Give a precise definition, using appropriate quantifiers etc. 2. When is R said to be an partial order? Give a precise definition, using appropriate quantifiers etc (You don't need to redefine things that you defined in the previous part... you may simply mention them to save time.) 3. On Z, define a relation: a D biff a - b is...
