Iterate, beginning with k= 0, a k+1 = 2a kb k a k+ b k; b k+1 = p a k+1b k: (68) Then both a k and b k converge to ˇ: each iteration decreases the distance between a k and b k (which interval contains ˇ) by a factor of approximately four.

      Theorem 9. The number log2 is irrational. Proof. Assume log2 = a/b for some integers a and b with b > 0. We will obtain a contradiction by showing there are integers c and d for which 0 < |c+dlog2| < 1/b. We use that, from Lemma 1, d n < e3n/2 for n sufficiently large. Observe that one of xn +1 and xn −1 is divisible by x+1 in Z[x]. Thus, xn ...
