In vector calculus, divergence is a vector operator that operates on a vector field, producing a scalar field giving the quantity of the vector field's source at each point. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point.
Learn the definitions and examples of divergence and curl of a vector field in two and three dimensions. Divergence measures how the field behaves towards or away from a point, while curl measures how the field rotates around a point.
- In Mathematics, a divergence shows how the field behaves towards or away from a point. Whereas, a curl is used to measure the rotational extent of...
- The divergence of a vector field is a scalar field, whereas the curl of a vector field is a vector field.
- The divergence of a vector field can be found by taking the scalar product of the vector operator applied to the vector field. That is, ∇ . F(x, y).
Divergence and curl are two important operations on a vector field. They are important to the field of calculus for several reasons, including the use of curl and divergence to develop some higher-…

a situation in which two things become different, or the difference between them increases: a divergence of opinion. The figures reveal a marked divergence between public sector pay settlements and those in the private sector.
- Vector Identities. Two computationally extremely important properties of the derivative \(\dfrac{d\ }{dx}\) are linearity and the product rule. \[\begin{align*} \dfrac{d\ }{dx}\big(af(x)+bg(x)\big) &=a\dfrac{df}{dx}(x)+b\dfrac{dg}{dx}(x)\\ \dfrac{d\ }{dx}\big(f(x)\,g(x)\big) &=g(x)\,\dfrac{df}{dx}(x)+f(x)\,\dfrac{dg}{dx}(x) \end{align*}\]
- Vector Potentials. We'll now further explore the vector potentials that were introduced in Example 4.1.9. First, here is the formal definition. The vector field \(\textbf{A}\) is said to be a vector potential for the vector field \(\textbf{B}\) if.
- Interpretation of the Gradient. In this section we'll develop an interpretation of the gradient \(\vecs{ \nabla} f(\vecs{r} _0)\text{.}\) This should just be a review of material that you have seen before.
- Interpretation of the Divergence. In this section we'll develop an interpretation of the divergence \(\vecs{ \nabla} \cdot\vecs{v} (\vecs{r} _0)\) of the vector field \(\vecs{v} (\vecs{r} )\) at the point \(\vecs{r} _0\text{.}\)
Learn how to compute and interpret the divergence of a vector field, which measures the change in density of a fluid flow. See examples, animations, and sources and sinks of divergence.
6 days ago · The divergence of a vector field F, denoted div(F) or del ·F (the notation used in this work), is defined by a limit of the surface integral del ·F=lim_(V->0)(∮_SF·da)/V (1) where the surface integral gives the value of F integrated over a closed infinitesimal boundary surface S=partialV surrounding a volume element V, which is taken to ...
