What have you done for yourself?
Can you give it a start at least?
Can you show the relation is reflexive?
I have a problem that asks about Equivalence of relations
Here is the problem:
a) Let R1 be the relation R1 = {(m,n) E Z X Z| |m| = |n|}. Show that R1 is an equivalence relation.
and
b) Find the equivalence classes of [0], [3], [-4] in R1
Any help would be great.
Thanks
