Derive gradient in spherical coordinates

WebMar 28, 2024 · That is simply the metric of an euclidean space, not spacetime, expressed in spherical coordinates. It can be the spacial part of the metric in relativity. We have this coordinate transfromation: $$ x'^1= x= r\, \sin\theta \,\cos\phi =x^1 \sin(x^2)\cos(x^3) $$ WebThe correct way to derive the curl in spherical coordinates would be to start with the Cartesian version and carefully substitute in our coordinate changes for the unit vectors and for (x,y,z) \rightarrow (r,\theta,\phi) (x,y,z) → (r,θ,ϕ).
