    could someone help me out. how to get from the LHS to the RHS here:

    [tex]\gamma (1 - \beta) \nu= \sqrt{\frac{1 - \beta}{1 + \beta}} \nu[/tex]

    where [tex]\gamma = \frac{1}{\sqrt{1 - \beta^{2}}}[/tex]

    thanks!

    so frustrating, i cant get latex do what i want and editing doesn't work. ok that should of course be 1 over the sqrt of 1 - beta^2

    It happens :tongue:

    Remember you can write

    [tex]1-\beta^2 = (1-\beta)(1+\beta)[/tex]

    EDIT: I see it changed again...will still work though.
