An intresting equation ? Taking squares by equation. tommy1729 Ultimate Fellow Posts: 1,859 Threads: 402 Joined: Feb 2009 05/08/2015, 11:37 PM Let g be An analytic function with attracting parabolic fixpoint at 0. ( hyperbolic might also be intresting ) I want to compute g(u)^2 + g(g(u))^2 + ... Instead of using super and Abel, work directly : F(x) = x^2 + F(g(x)) Now the intresting things are 1) g is a polynomial 2) taking the 3rd derivative of the equation.
