+2592 What you may have seen is either a hybrid your mind made up or a typo as
sqrt(1-v^2/c^2) is the same as (1-v^2/c^2)^.5
I have dealt in these formulas however so I do not know
The formula is: 1/ [Sqrt(1 - V^2)], where V=fraction of the speed of light. Example: A spaceship is travelling at .99 of the speed of light, calculate the time passed on the spaceship compared to the time elapsed on Earth.
1/ [Sqrt(1 - .99^2)]=1/ [Sqrt(1 - .9801)]=1/[Sqrt(0.0199)]=1/0.141067=7.0888. This is the time elapsed on Earth(in years if you wish), while 1 year has passed on the spaceship.
