In this tutorial, we will discuss how you can use the gradient operator in latex documents.

Scientifically, the gradient operator is denoted by the nabla(∇) symbol. And the gradient is always written in the form of a partial derivative.

```
\documentclass{article}
\begin{document}
$$ \nabla $$
$$ \nabla =\frac{\partial }{\partial x}\hat{\imath} + \frac{\partial }{\partial y}\hat{\jmath} +\frac{\partial }{\partial k}\hat{z} $$
\end{document}
```

**Output :**

You need to use `\imath`

and `\jmath`

instead of unit vectors i and j. As a result, there will be no dots on the heads of i and j and that would look nice with the z unit vector.

Suppose, if the function is f. Then will be the gradient of the function

```
\documentclass{article}
\begin{document}
$$ \nabla f = grad \: \textit{f} $$
$ $\nabla f=\frac{\partial f}{\partial x}\hat{\imath} + \frac{\partial f}{\partial y}\hat{\jmath} +\frac{\partial f}{\partial k}\hat{z} $$
\end{document}
```

**Output :**

You can easily represent the above tasks with the help of the physics package. And the best practice is to use a `physics`

package for gradient operators.

## Use physics package for gradient operator in LaTeX

The gradient command is used to define the gradient operator in physics packages. And the `\gradient`

command is represented by `\grad`

in short form.

```
\documentclass{article}
\usepackage{physics}
\begin{document}
$$ \grad F(x,y,z)$$
\end{document}
```

**Output :**

The gradient operator is a vector. That is, you can denote the nabla(∇) symbol with a vector arrow above the nabla(∇) symbol without making it bold.

```
\documentclass{article}
\usepackage[arrowdel]{physics}
\begin{document}
$$ \grad f$$
\end{document}
```

**Output :**

As you can see in the program above,` arrowdel`

has been used as an optional argument with the `physics`

package for vector arrow.
