| Jun 3, 2023 at 17:56 | comment | added | Carlo | Oh I see a vector made of partial derivatives using Cartesian coordinates. I'd assume this vector can take many forms, 1x3, 2x3, 3x3... or does that exclude it from being "covariant." Also your right, I probably will not be able to understand covariance. | |
