- Homework Statement
- I do not understand the mathematical formula under item 1. at all (and not the other items either).

- Relevant Equations
- The text says: "1. If we insert the 4-velocity u of the observer into one of the slots...". I do not understand at all. What does it mean that a tensor has "vector slots"? What does "dp/dV" mean? I would like to see the operation step by step.

I have attempted but with no result.
