I imagine that you want the relativistic formula, that I
implemented in a Javascript at...

The formulas for the acceleration phase [double when
appropriate for the deceleration phase] are:
t (unaccelerated) = c/a * sinh(a*t/c)
d = c**2/a * (cosh(a*t/c) - 1)
v = c * tanh(a*t/c)
where c = speed of light, a = acceleration _relative_ to the
rocket passengers, t = time relative to the passengers,
t(unacc.) = time relative to the "galaxy",
d = distance in the "galaxy" travelled by the rocket,
v = speed of the rocket relative to the "galaxy"
The non-relativistic is trivial. No, I am not a _star_ship pilot,
just a _space_ship pilot. My ships have never gone
much farther than the Moon.
