Hi there,

Can someone give me a push in the right direction?

I have this assignment I have to make, I study beta gamma with math as a major.

This is the question:

A is a non empty set, and X1 and X2 are equivalence relations on A. X is also an equivalence relation on A, because X = the set of the element that are X1 and X2.

T1 is the partition of A that corresponds to X1, and T2 is the partition of A that corresponds to X2. T is the partition that corresponds to X.

The question: What is the relation between T1, T2 and T?

I also have to prove it, but I think I can do that myself...if I know which way to go.
