I've derived the spherical unit vectors but now I don't understand how to transform cartesian del into spherical del at all. WebThe vector (x, y, z) points in the radial direction in spherical coordinates, which we call the direction. Its divergence is 3. A multiplier which will convert its divergence to 0 must therefore have, by the product theorem, a gradient that is multiplied by itself. The function does this very thing, so the 0-divergence function in the direction is.
