####### physics #######
The physics extension implements much of the LaTeX physics package <https://ctan.org/pkg/physics?lang=en>_, which defines simple, yet
flexible, macros for typesetting equations via:
|btight|
|etight|
See the documentation <https://mirrors.ctan.org/macros/latex/contrib/physics/physics.pdf>_
for the LaTeX package for more information.
This package is not autoloaded, due to the fact that it redefines many
standard macros, so you must request it explicitly if you want to use
it. To load the physics extension, add '[tex]/physics' to the
:data:load array of the :data:loader block of your MathJax
configuration, and add 'physics'`` to the :data:packages array of the :data:tex` block.
.. code-block:: javascript
window.MathJax = { loader: {load: ['[tex]/physics']}, tex: {packages: {'[+]': ['physics']}} };
Alternatively, use \require{physics} in a TeX expression to load it
dynamically from within the math on the page, if the :ref:tex-require
extension is loaded.
.. _tex-physics-options:
Adding the physics extension to the :data:packages array defines an
:data:physics sub-block of the :data:tex configuration block with the
following values:
.. code-block:: javascript
MathJax = { tex: { physics: { italicdiff: false, arrowdel: false } } };
.. _tex-physics-italicdiff: .. describe:: italicdiff: false
This corresponds to the italicdiff option of the physics LaTeX package to
use italic form for the d in the \differential and \derivative
commands.
.. _tex-physics-arrowdel: .. describe:: arrowdel: false
This corresponds to the arrowdel option of the physics LaTeX package to
use vector notation over the nabla symbol.
Note, that the physics extension does not implement the notrig option.
.. _tex-physics-commands:
The physics extension implements the following macros:
