 Author Comment/Response the_wOnderer 03/13/12 12:07pm I'm trying to solve a system of First Order ODEs. NDSolve[{Subscript[y, 1]'[t] == Cos[Subscript[y, 3][t]], Subscript[y, 2]'[t] == Sin[Subscript[y, 3][t]], Subscript[y, 3]'[t] == (( Cos[Subscript[y, 3][ t]] - (Sin[Subscript[y, 3][t]] Abs[Sin[Subscript[y, 3][t]]]))/ Subscript[y, 4][t]), Subscript[y, 4]'[t] == Sin[Subscript[y, 3][ t]] - (Cos[Subscript[y, 3][t]] Abs[Cos[Subscript[y, 3][t]]]), Subscript[y, 1][0] == Subscript[y, 2][0] == Subscript[y, 2][1] == 0, Subscript[y, 1][1] == 0.75}, {Subscript[y, 1], Subscript[y, 2], Subscript[y, 3], Subscript[y, 4]}, {t, 0, 1}, Method -> "Shooting"] Can anyone tell me why the following errors occur? Power::infy: NDSolve::ndnum: And also, how to go about solving this one? Thanks! URL: ,
