Homework Equations
The Attempt at a Solution
Since I'm terrible with Latex I took a picture of what I have so far. I'm not sure where to go next or if I'm even on the right track.
My professor gave a hint that u'^2=(ux')^2+(uy')^2+(uz')^2
And that (u'/c)^2[itex]\Rightarrow[/itex]1(u'/c)^2[itex]\Rightarrow[/itex] 1/(1(u'/c)^2)^1/2
which I think just confused me more.
Thanks a lot
