Is divergence a linear operator
WebMay 31, 2016 · Calculating divergence is much simpler: If we want to calculate the Divergence for F (x,y) = (x^2 * y, xy) at (5,4), all we need to do is take the dot product of F (x,y) with the (∂/∂x, ∂/∂y) operator: Div (F (x,y)) = ∂/∂x (x^2 * y) + ∂/∂y (xy) = 2xy + x = 2 (5) (4) + (5) = 40 + 5 = 45. No unit vectors vectors or directional vectors needed.
