Divergence of v
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 … Webamadeusz.sitnicki1. The graph of the function f (x, y)=0.5*ln (x^2+y^2) looks like a funnel concave up. So the divergence of its gradient should be intuitively positive. However after calculations it turns out that the divergence is zero everywhere. This one broke my intuition.
