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!
