The LaTeX command for nabla gradient (∇) is \nabla (gradient / del operator).
\nablaWriting a paper? The table generator and the BibTeX cleaner are one click away, no account.
| Command | Package | Use it when |
|---|---|---|
\nabla f recommended | none | Gradient of a scalar field. |
\nabla \cdot \mathbf{F} | none | Divergence. |
\nabla \times \mathbf{F} | none | Curl. |
\nabla^2 f | none | Laplacian, also written \Delta f. |
\boldsymbol{\nabla} | amsmath | Bold nabla, when vectors are bold. |
Write \nabla inside math mode, that is between $…$ for inline math or in a \[ … \] or equation block for display math. It is part of core LaTeX math, so no extra package is required.
$\nabla \cdot \mathbf{E} = \frac{\rho}{\varepsilon_0}$Open this example in the live preview: it renders as you type, with no compiler and no signup.

Use \nabla in math mode; it needs no extra package. For example, $\nabla \cdot \mathbf{E} = \frac{\rho}{\varepsilon_0}$.
None: \nabla is built into LaTeX, so no extra package is required.
\nabla f alone is the gradient, a vector. The Laplacian is \nabla^2 f or \Delta f, a scalar.
