I only recall checking the relativistic acceleration/time/distance
program, but it was incorrect.
The correct equation to use is:
t = c / a * acosh(1 + a * d / c^2)
where
a = acceleration (m/s^2)
d = distance (m)
t = time (s)
c = speed of light (m/s) (duh)
acosh = inverse hyperbolic cosine
I recall the program in the LIT archives used alog (inverse common
logarithm) instead, apparently because it was translated from BASIC to C
by a rather poor automated translator.
