Homework Statement
http://books.google.com/books?id=Xm...42EpgKaxsi5Dw&sig=6cUrZKqmPMoe0QBRTSYNnipNRw4
In problem 6.1, I am trying to show "why the following relations hold"
for the first one, that would just be the definition of ds^2 if you had (cdt)^2 in there but I cannot figure out what happened to it
for the the second one, I am confused about how that can possible be write because the expression for v_perp on 110 implies that it is a vector with the same number of components as X^mu but the y has two fewer components than X. What gives?
