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. WebThe gradient of function f in Spherical coordinates is, The divergence is one of the vector operators, which represent the out-flux's volume density. This can be found by taking the dot product of the given vector and the del operator. The divergence of function f in Spherical coordinates is, The curl of a vector is the vector operator which ...
