I have some problem with Mathematica. I have to solve a system of 2 ordinary differential equation, and inside theese equations i have a parameter H, the initial conditions and final time that vary. So i use manipulate and NDSolve, but it doesn't work! i've tried in two differents way: in the first it doesn't plot and in the second it gives me strange results, for exemple a dipendence from the initial conditions too strongly and limit cicles that disappear for some initial values or for some tmes value totally random!! I attached the file i have done with mathematica [Contact the author to obtain the attachment - Moderator] thank you very much! Silvia Pierazzini
