The question is:
Let $A = \{1, 2, 3, 4, 5\}$ and
Let $R = \{ (3,4), (5,5), (1,1), (2,2), (5,2), (1,4), (2,5), (3,1), (3,3), (4,1), (1,3), (4,3), (4,4)\}$ be an equivalence relation on A.
Find the [$1$] and [$3$] on $R$.
I understand what an equivalence relation is (reflexive, symmetric and transitive), but I've been trying to find what the professor wants me to do but I can't figure out what he wants by [$1$] and [$3$]. What does he mean by find [$1$] and [$3$]? Does he want me to find the sets that make up the reflexive and transitive properties?
