Web16 apr. 2024 · Is that fixed-point iteration fixed? From x 2 = 2 + x one finds the better iteration x n + 1 = 2 + x n for the positive root. – Lutz Lehmann Apr 16, 2024 at 16:25 Yes, but I thought the reason it’s ‘better’ is because it satisfies abs (g’ (x))<1 in some interval. But g (x) in op works just fine up to -+1. – AKubilay Apr 16, 2024 at 18:10 Web26 jan. 2024 · Bisection Method, Newtons method, fixed point,...
