The beta factor as given here is inconsistent with the page https://en.wikipedia.org/wiki/Lorentz_factor which is also referenced. The beta factor given here is actually the definition of gamma factor and beta should be the square root of (v/c)^2. If gamma is dt/dtau as given here then the proper expression for gamma is derived.
