Divergence operator is written in the form of the dot product of gradient operator(**∇**) and vector.

div **F**= **∇** • **F (vector)
**

First, you can represent the divergence operator by arranging the individual symbols (nabla, dot, vector) one after the other.

```
\documentclass{article}
\begin{document}
\[ \mathbf{\nabla} \cdot \mathbf{F} \]
\[ \mathbf{\nabla} \cdot \mathbf{F}=\frac{\partial F_{x}}{\partial x} + \frac{\partial F_{y}}{\partial y} + \frac{\partial F_{z}}{\partial z} \]
\end{document}
```

**Output :**

You notice that the output above is bold without the arrow symbol on **F**. And, this is the best practice with nabla(∇) symbol.

Second, you can represent the divergence operator with the help of `physics`

package. This is because the `\div`

command is present in this `physics`

package. In which if you pass the vector as an argument, the divergence operator will return to you.

```
\documentclass{article}
\usepackage{physics}
\begin{document}
\[ \div \]
\[ \div{\vb{F}} \]
\[ \div(\vb{F_{1}+F_{2}}) \]
\[ \div[\vb{F_{x},F_{y},F_{z}}] \]
\end{document}
```

**Output :**

In latex, it is best practice for divergence operators to use `physics`

packages rather than using each symbol individually.
