Question: Example We showed earlier that the relation p defined on the set of ordered pairs R x R by (any) p(p,q) iff :1: + q

Example We showed earlier that the relation p defined on the set of ordered pairs R x R by (any) p(p,q) iff :1: + q = y +p is an equivalence relation. '7) (i) Determine the equivalence class of (0, 0) (ii) Determine the equivalence class of (1, 2)? What is the relationship between [(0, )] and [(1, 2)]? EXAMPLE Let R be relation on a set Z+ such that x Ry, if and only if log2 is an integer . 1. Is R an equivalence relation? 2. If so, find [4]
