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.

Divergence operates on a vector field but … WebThere is an equation chart, following spherical coordinates, you get ∇ ⋅ →v = 1 r2 d dr(r2vr) + extra terms . Since the function →v here has no vθ and vϕ terms the extra terms are zero. Hence ∇ ⋅ →v = 1 r2 d dr(r21 r2) = 1 r2 d dr(1) = 0. At least this is how I interpret the surprising element of the question. Share. mike\u0027s off road \u0026 motocross safety class
