I should have mentioned that at time t1 the coordinates for that point will
be:

<x_fn(x0, y0, z0, t1), y_fn(x0, y0, z0, t1), z_fn(x0, y0, z0, t1)>


And that another point with these coordinates:

<x1, y1, z1>

- at time t0 will have these coordinates:

<x_fn(x1, y1, z1, t0), y_fn(x1, y1, z1, t0), z_fn(x1, y1, z1, t0)>

(I see now that it would probably have been better if I had denoted time
values as tA, tB, tC and so on.)
