I solved Newton's equation to get a particle's trajectory, with Mathematica 4.2. Mma gives me this code as OutPut :

{{x -> InterpolatingFunction[{{0., 50.}}, "<>"], y -> \
InterpolatingFunction[{{0., 50.}}, "<>"],
z -> InterpolatingFunction[{{0., 50.}}, "<>"]}}

I can get the graphs in 3D from this, and the curve is very nice. But I need all the cartesian coordinates of the points on that curve, according to the resolution used. How can I tell Mma to show me explicitely the points drawn, in a list form ? I need something like this (with numbers) :

{{ x1, y1, z1}, { x2, y2, z2}, { x3, y3, z3}, . . . }
