Let x_0 be a real number in the interval (0,1] and {x_n} be sequence for all n >= 0, defined inductively by setting x_n = sin(x_(n-1)) for all n >= 1. I have already proved that {x_n} is a strictly decreasing sequence in (0,1] and that the lim x_n asn→∞ = 0.
We need to prove parts 2 and 3 in the attachment!
Thanks!
