Homework Help Overview

The discussion revolves around the interpretation of a derivation task in a general relativity course, specifically regarding the change in a vector under parallel transport as referenced in lecture notes.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the nature of the derivation requested by the professor, questioning whether it involves re-writing existing steps or filling in missing details. There is uncertainty about the completeness of the lecture notes and what constitutes a proper derivation in this context.

Discussion Status

The discussion is ongoing, with participants sharing their interpretations and uncertainties about the professor's expectations. Some guidance is offered regarding the typical nature of lecture notes, suggesting that a more thorough approach may be desired.

Contextual Notes

Participants note the lack of response from the professor to clarify the assignment, which contributes to the ambiguity in understanding the task requirements.

Homework Statement



This seems like a simple question but I've never asked it and I'm stuck haha
For my general relativity course we are asked to derive the change in a vector under parallel transport. My professor references his lecture notes on his course web page in the statement of the problem...he says "In the notes, derive all the steps in eq. 1.8"

But in the lecture notes the equation 1.8 seems to be the derivation itself. I.e. he has several steps of tensor analysis and arrives at the conclusion and says the final answer, that a vector does not change under parallel transport. This is what I would have considered a derivation.

Do you think he wants to re-write the steps already laid out for us and maybe write some side comments to show we understand what's going on in each step? Or is a derivation something else entirely?

and yes I did try to ask him about this but no luck on an email response. thanks!

The Attempt at a Solution

Are there lots of steps missing in the notes? Maybe he just wants you to fill in all the gaps needed to get to this eq. 1.8. Usually lecture notes only have really brief and sketchy ("hand-waving") derivations of things, so he probably just wants you to do it more thoroughly.

That's what I thought... but the equalities and substitutions to derive further results are very well laid out and "easy" to follow. (easy meaning comprehensive)
 
Well, then I'm out of ideas :p.
