Deriving Gamma(v): Start with Galilean Transformation

[Ivy_Mike]

I would like to derive gamma(v), by starting with the galilean transformations for x and x'. Knowing that t=t'=0, if a light pulse is emitted at the origin of S then the ratio t'/t should somehow be eliminated from the two equations. From there, one can obtain gamma(v).

Any ideas?

You derives $\gamma$ from the postulates of relativity. I would suggest you get a book on special relativity and see how it is derived.
