 Author Comment/Response iss 07/20/12 03:47am I tried to solve some Nonlinear equation with variable 'r' (a,b,d,[gamma],[Theta], etc are just number) which is (Sqrt[a^2 + b^2] - r) Sec[\[Gamma] + ArcSin[(r Sin[\[Theta]])/Sqrt[ d^2 + r^2 - 2 d r Cos[\[Theta]]]]] Sin[\[Theta]] == 0 There are several cases depends on the values of a,b,d,[gamma],[Theta]. There can be complex and non positive solutions, Only I want to get is positive Numeric (NOT Analytic!) solutions. But in some cases, I faced "Solve::ratnz: Solve was unable to solve the system with inexact coefficients. The answer was obtained by solving a corresponding exact system and numericizing the result." I know thie is just warning, but the problem is solving time is very long in this cases. One cases need is around 3~4 seconds but I have to solve more than million cases. So I have to avoid this warning or I have to try to another approach. Is there any solutions? Thank you in advance! URL: ,
