all parts A-E please. Problem 8.43. For sake of a contradiction, assume the interval (0,1) is countable. Then there exists a bijection f : N-> (0,1). For each n є N, its image under f is some number in (0, 1). Let f(n) :-0.aina2na3n , where ain 1s the first digit in the decimal form for the image of n, a2 is the second digit, and so on. If f (n) terminates after k digits, then our convention will be...

Real Analysis II Please do it without using Heine-Borel's theorem and do it only if you're sure Problem: Let E be a closed bounded subset of En and r be any function mapping E to (0,∞). Then there exists finitely many points yi ∈ E, i = 1,...,N such that Here Br(yi)(yi) is the open ball (neighborhood) of radius r(yi) centered at yi. Also, following definitions & theorems should help that E CUBy Definition. A subset S of a topological...
The definition we gave for a function is a bit ambiguous. For example, what exactly is a "rule"? We can give a rigorous mathematical definition of a function. Most mathematicians don't use this on an everyday basis, but it is important to know that it exists and see it once in your life. Notice this is very closely related to the idea of the graph of a function. Definition 9. Let X and Y be sets. Let R-X × Y...
