1. A straight line in flat space may be defined by the equation:
(when I use the ^ symbol in this case it means like upper subscript not to the power)
(U^v)(d/dx^v)(U^u)=0
(U^u=dx^u/ds)
derive the geodesic equation.
Please help I'm completely clueless all I can really see to do is mix the two equations but that doesn't really show me anything more clearly, any help would be greatly appreciated.
