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!
