Suppose S+ 2πa intersection S+2πb contains some angle x. Hence x= y + 2πa= y'+2πb hence y , y' both belongs to S(x) and S contains exactly 1 element from S(x) hence y= y' and a=b . Hence these 2 sets are identical. Hence any two sets S+2πa and S+2πb either disjoint or identical

Identify the correct steps involved in proving that the union of a countable number of countable sets is countable. (Check all that apply.) Check All That Apply Since empty sets do not contribute any elements to unions, we can assume that none of the sets in our given countable collection of countable sets is an empty set. If there are no sets in the collection, then the union is empty and therefore countable, Otherwise let the countable sets be As,...

2. In this problem, we will prove the following result: If G is a group of order 35, then G is isomorphic to Zg We will proceed by contradiction, so throughout the following questions, assume that G is a group of order 35 that is not cyclic. Most of these questions can he solved independently I. Show that every element of G except the identity has order 5 or 7. Let...
