The notation in typical electrodynamics textbooks isn't very transparent with respect to the issues you're raising. Indeed, the hatted basis vectors are used, but the unhatted coordinates! If you replace also the unhatted coordinates with the hatted ones in the usual expression, then it seems to me things are consistent with your way of looking at it. | |

Nov 23, 2019 at 21:30 | comment | added | Craig | Thank you for clarifying this for me. I do have a follow up question if you have the time: in this answer (math.stackexchange.com/questions/618031/…) ∇ is derived for spherical coordinates. However in my case $\hat{∇}$ would have no pre-factors, since all of my dual vectors would be of length 1. This is not at all the usual ∇ operator found in, say electrodynamics textbooks, where that hatted cooridnate basis is certainly the one being used. | |
