Grad in cylindrical polars

WebA key property of Grad is that if chart is defined with metric g, expressed in the orthonormal basis, then Grad [g, {x 1, …, x n]}, chart] gives zero. Coordinate charts in the third argument of Grad can be specified as triples { coordsys , metric , dim } in the same way as in the first argument of CoordinateChartData . WebMar 23, 2024 · In my electromagnetism text (undergrad) there's the following statements for. position vectors in cylindrical coordinates: r → = ρ cos ϕ x ^ + ρ sin ϕ y ^ + z z ^. I understand this statement, it's the following, I don't understand how a 3D position can be expressed thusly: r → = ρ ρ ^ + z z ^. Thanks for any insight and help!
