Hi, I am a freshman of Mathematica, I need help here... I met such problem as: NDSolve[{ y'[x] == -\[Rho]y[x], y[0] == Subscript[y, 0], I\[HBar] y'[x] == \[Epsilon]y[x], y[0] == Subscript[y, 0], y''[x] + 2 \[Rho]y'[x] + k^2 == 0, y'[0] == Subscript[g, 0]}, y, x] NDSolve::dvnoarg: The function y appears with no arguments. How to Handle???
