I need help

[wabafet]

I have an mathematical problem, and I don't even know how to start it.
I have two relations of equivalence R1 and R2. And I have to examine the relation R1∩R2.

Any equivalence relation must be reflexive, symmetric, and transitive.
Since both \(\displaystyle R_1~\&~R_2\) are equivalence relations you must examine \(\displaystyle R_1\cap R_2\) for those three properties.
