Time in the Lorentz transformation

    where does t`=(t-vx/c^2)/(1-v^2/c^2)^1/2 come from?

    From
    [tex] \left( \begin{array}{c} x' \\ t' \end{array} \right) = \left( \begin{array}{cc} cosh(\theta) & -sinh(\theta) \\ sinh(\theta) & cosh(\theta) \end{array} \right) \left( \begin{array}{c} x \\ t \end{array} \right) [/tex]

    where [tex]v = tanh(\theta)[/tex] and c is taken to be 1.

    It should be [tex]+\sinh(\theta)[/tex].
    (The determinant has to be 1.)

    Or rather they should both be [tex]-\sinh(\theta)[/tex] I believe.
