I'm sorry, I'm new to mathematica, and don't know the syntax by heart yet (and what kind of variable each function returns). Iv'e changed the boundaries to 0-100 in both case. Still doesn't work. I know, I still need to change the input as to plot y instead of NDSolve. Not that I know how to...

Thanks! By the way, is NDSolve compatible with Manipulate? I've tried combining the two with little success: Manipulate[ Plot[NDSolve[{y''[x]*(y[x] + eps/y[x]) == -0.5 y'[x] y'[x], y[0] == 75*((4/675)^(1/3)), y'[0] == -(4/675)^(1/3)}, y, {x, 0, 48}], {x, 0, 100}], {eps, 0...

Hello, I'm trying to (numerically) solve the equation y''*y=-0.5*y'^2 in Mathematica. I know there's an analytic solution (and I know how to calculate it), but I want to modify this equation and thus need to verify that the numerical solution for the original equation is exact. I'm using...
