Well, unless you have a nice system of parametric equations for the curve (which I don't believe you do), you'll have to replace, eg x' with (Delta x)/ (Delta t) (forgive the crude math notation, since SO doesn't support LaTeX). Since your intervals are all one second apart, Delta t is 1, so you can replace x' with Delta x and likewise with ...
