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.

In three-dimensional Cartesian coordinates, the divergence of a continuously differentiable vector field is defined as the scalar-valued function: Although expressed in terms of coordinates, the result is invariant under rotations, as the physical interpretation suggests. This is because the trace of the Jacobian matrix of an N-dimensional vector field F in N-dimensional space is invariant under any invertible linear transformation.
