Re: Composition and Invertible Proofs
Your notation looks a bit weird to me. Is that exactly from a question? What normal notation would be:
Notice how you can go from A>B and then from B>C. But remember, that f and g are invertible, so you can go from B>A and from C>B. Use this, and show that if an element is in C, then the element must correspond to some element in A. "In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..." #3 20060303 21:32:41
