... while the sequence {A2n−1} is strictly decreasing, i.e.,A0< A2< ··· < A2m< ··· < A2n−1< ··· < A3< A1.Theorem 1.35. The convergents of the infinite continued ... there must be a factorization n0= uv withu, v ∈ N0 and u, v = 1. Then we have 1 < u < n0 and 1 < v < n0, hence u, v /∈ S and so thereare factorizationsu = p1···pr, v = ... of a/b and −a/b, b/awhen a, b are non-zero natural numbers. 1-1 7. If A = [a0; a1, . . . , an] with A > 1, show that 1/A = [0; a0, a1, . . . , an].Let x > 1 be a real number. ...
