Describe the equivalence classes
WebThis equivalence relation partitions our class into subsets where everyone in a given subset is related to everyone else in that subset, no person is in two different subsets, and the union of all the subsets is the entire class. The next definition gives us a name for the subsets in the partition. 🔗. Definition 8.16.
