2012-02-03 17:21:13 +0100 asked a question join lists?

Hello! Is there a way to join two lists? For example, v=[1,2,3]; w=[4,5,6];

how can I obtain the list z=[1,2,3,4,5,6]? Thank you very much, Francesco

Yes, I corrected my original post with the equations I need to solve numerically

Hi everybody! I would like to know whether there exists a simple way to solve in a numerical way a system of non linear equations (the system cannot be solved analytically). In particular, the system (in the variables a,b) I'd like to solve is the following:

-2(ab/sqrt(-1/2a^2 + b^2) - 2/(a^2b^2))(sqrt(-1/2a^2 + b^2)b - 1/(ab^2)) - 16/(a^5*b^2)=0

4b^3 + 4(sqrt(-1/2a^2 + b^2)b - 1/(ab^2))(b^2/sqrt(-1/2a^2 + b^2) + sqrt(-1/2a^2 + b^2) + 2/(ab^3)) - 8/(a^4b^3)=0

Thanks in advanced, Francesco
