Equivalence Classes of an Equivalence Relation
The distinct equivalence classes of an equivalence relation on a set A provide us with a decomposition of A as a union of mutually disjoint subsets.
Conversely, given a decomposition of A as a union of mutually disjoint, nonempty subsets, we can define an equivalence relation on A for which these subsets are the distinct equivalence classes.
Or, An equivalence relation over a set induces a partition of the set. Conversely, a partition of a set defines an equivalence relation.

The distinct equivalence classes of an equivalence relation on a set provide us with a decomposition of as a union of mutually
disjoint subsets.
Conversely, given a decomposition of as a union of mutually disjoint, nonempty subsets, we can define an equivalence relation
on for which these subsets are the distinct equivalence classes.
Or,
An equivalence relation over a set induces a partition of the set. Conversely, a partition of a set defines an equivalence relation.
Solution:- Let ~ be an equivalence relation on a set .
For any ,
We have to prove that the equivalence relation ~ over the set decomposes the set as a union of mutually disjoint
