... Every element of S is irrational, but S has the same cardinality as Q and hence is countably infinite. Also, S is dense in R as it is just a shifted version of Q. 3 For each sequence below determine whether it converges and, if it converges, find its limit. No proofs are required. a: an = n/(n + 1) ...

... ∴ the smallest number in the sum of 25 consecutive whole numbers is 28. Note: The sum simplifies to 25n = 1000 because for each positive integer 1 to 12 in the sum the opposite integer -1 to -12 also appears. Then (1 + 2 + · · · + 11 + 12) + (−1 − 2 − · · · − 11 − 12) = 0. Solution 3 In Problem C th ...

... Prime numbers and composite numbers play an important role in almost every branch of mathematics. A prime number is a positive integer greater than 1 that has no positive-integer factors1 other than itself and 1. The 10 smallest prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. Each of these ...

... Note that a(x) is a monic polynomial of degree 1008, while b(x) is a monic polynomial of degree 1007. Therefore, p(x) = a(x) − b(x) is a monic polynomial of degree 1008. • Suppose that 1 ≤ m < 2015 is an integer congruent to 1 modulo 4. Then we have a(m) = 0, b(m) < 0, b(m + 1) = 0, and a(m + 1) < 0 ...
