How to find the first negative derivative ? - tommy1729 - 02/13/2017
Sign theory Consider f(x) = 0 + A1 x + A2 x^2 + ... Where f is entire and all n th derivatives are positive. Also f(x) > x for x > 0 and the fixpoint at 0 is hyperbolic. Also there are no there are no other fixpoints within or on the unit radius. Now use the usual method to find the half iteration g(x). How to efficiently find the first n th derivative ( Of g(x) at x = 0 ) < 0 ?? Regards Tommy1729 |
