Velocity-addition formula
Deleted assertion that: "The initial requirement that the first operand refers to the velocity of a ''frame'' is nowhere used", as it was used as the initial requirement. The lesser requirement that v is colinear with x is what has been dropped.

Velocity-addition formula
I think this this statement about adding boosts velocities is probably true. I am not convinced it has been derived on this page. Perhaps it has. A citation from a reference would be good here.
