WebThe symbol for divergence is the upside down triangle for gradient (called del) with a dot [ ⋅ ]. The gradient gives us the partial derivatives ( ∂ ∂ x, ∂ ∂ y, ∂ ∂ z), and the dot product with our vector ( F x, F y, F z) gives the divergence formula above.

In the DA models, the difference between

WebDivergence and Green’s Theorem. Divergence measures the rate field vectors are expanding at a point. While the gradient and curl are the fundamental “derivatives” in two dimensions, there is another useful measurement we can make. It is called divergence. It measures the rate field vectors are “expanding” at a given point.
