I'm wondering if someone could briefly explain how I can determine the equivalence class of relation? I understand that first you must test the relation to see if is true for the properties, reflexive, symmetric, and transitive. But my main problem is once that is done how can I get the equivlant class of that. My book that I'm using does a terrible job in explaining the theorm, and hence it is very difficult for me to solve the practice problems. Thanks!
