An equivalence relation |
2008-08-27 |
|
From Francesca:
In this problem we are told to find out if the given set is an equivalence relation or not.
{(x,y) such that 4 divides x-y}. What I am confused about is whether or not for instance if I picked (1,5) as a part of the set whether I could put in (5,1) as well or whether that would be wrong. Thanks!
