Hi, been reading about GR and am quite confused about the new definition of vectors.
My main problem with this is that the text uses partial derivatives as the vector basis, I understand this is related to directional derivatives but cannot see the direct mathematical relation. Secondly, how are physical quantities defined in GR if we cannot use the line-segment definition of vectors?
