    How to begin proving set operations with disjoint unions

    Thank you very much, I think I see how I can proceed from here :) So basically it's all a matter of re-writing these to be easier to prove, eh?

    How to begin proving set operations with disjoint unions

    ah, shoot, yes >.< you're correct, it should be this: 1: Prove A is the disjoint union of A\B and A intersect B. That's what i get for trying to mess around with these symbols, I have no idea how to do it correctly on these boards and didn't even notice I had made a union sign instead of an...

    How to begin proving set operations with disjoint unions

    Well, I'm still confused why we're turning "and" into the union symbol. Is that what we're supposed to do? As far as A\B = A intersect B-compliment, I understand that. Everything in A that's not in B is equal to everything that's in both A and everything that's not in B, and also in A. But but...

    How to begin proving set operations with disjoint unions

    OK, I had a slight mistake in the problem. There are two separate but similar problems, and I got confused about which one I was reading half-way through the problem. I've updated them in the original post, and will repeat it here as well: Let A and B be any sets. 1: Prove A is the disjoint...

    How to begin proving set operations with disjoint unions

    Homework Statement Let A and B be any sets. 1: Prove A is the disjoint union of A\B and A intersect B. 2: Prove A U B is the disjoint union of A\B, A intersect B, and B\A. Homework Equations ? The Attempt at a Solution I understand most of the basic terminology used. I know disjoint...
