The question is let E1 and E2 be equivalence relations on set X. A new relation R is defined as the E1 o E2, the composition of the two relations. We must prove or disprove that R is an equivalence relation.
Homework Equations
The Attempt at a Solution
I know that we must prove
1) reflexive - this is easy just E1 = E1
2) symmetric
3)transitive
but I am unsure of how to prove the last two.
Thanks for any help in advance and if you need more information I will try to provide.
