hyperbolic trajectory

Anyone have a good website for how to determine the position along
hyperbolic trajectory(or what elements needed to calculate it, e.g
velocity at perigee, radius...), I just read through the notes about
determine the position along the elliptical orbit, but notes doest say
how to calculate it for hyperbolic trajectory.

Wikipedia seems to have the answers you're looking for. I don't know
whether they are correct of course...

Thanks for the reply Mark.

I found the equations for the problem its just similar to kepler's
equation for ellipse.

does anyone know how long does it take for a spacecraft to reach the
Sphere of Influence point on a hyperbolic trajectory using small delta-
v 's ?

Conic sections rings a bell... trajectories are all slices through a cone.
