MATH 115B PROBLEM SET V MAY 17, 2007 (1) Compute the continued fraction expansion of: (a) 7; (b) (1 + 13) / 2. (2) Evaluate the following infinite simple continued fractions: (a) [ 2 , 3]; (b) [0; 1 , 2 , 3]. (3)(a) For any positive integer n , show that n 2 + 1 = [ n ; 2 n ], n 2 + 2 = [ n ; n, 2 n ] and n 2 + 2 n = [ n ; 1 , 2 n ]. [Hint: Notice that n + n 2 + 1 = 2 n + ( n 2 + 1 - n ) = 2 n + 1 n + n 2 + 1 . ]
