Autmatic Equation Numering
==========================
New in MathJax v2.0 is the ability to have equations be numbered
automatically. This is off by default, so that pages don't change
when you update from v1.1 to v2.0, but it is easy to configure MathJax
to produce automatic equation numbers by adding:
.. code-block:: html
<script type="text/x-mathjax-config">
MathJax.Hub.Config({
TeX: { equationNumbers: { autoNumber: "AMS" } }
});
</script>
to your page just before the ``<script>`` tag that loads
``MathJax.js`` itself.
Equations can be numbered in two ways: either number the AMSmath
environments as LaTeX would, or number all displayed equations (the
example above uses AMS-style numbering). Set ``autoNumber`` to
``"all"`` if you want every displayed equation to be numbered.
You can use ``\notag`` or ``\nonumber`` to prevent
individual equations from being numbered, and ``\tag{}`` can be used
to override the usual equation number with your own symbol instead.
Note that the AMS environments come in two forms: starred and
unstarred. The unstarred versions produce equation numbers (when
``autoNumber`` is set to ``"AMS"``) and the starred ones don't. For
example
.. code-block:: latex
\begin{equation}
E = mc^2
\end{equation}
will be numbered, while
.. code-block:: latex
\begin{equation*}
e^{\pi i} - 1 = 0
\end{equation*}
won't be numbered (when ``autoNumber`` is ``"AMS"``).
You can use ``\label`` to give an equation an identifier that you can
use to refer to it later, and then use ``\ref`` or ``\eqref`` within
your document to insert the actual equation number at that location,
as a reference. For example,
.. code-block:: latex
In equation \eqref{eq:sample}, we find the value of an
interesting integral:
\begin{equation}
\int_0^\infty \frac{x^3}{e^x-1}\,dx = \frac{\pi^4}{15}
\label{eq:sample}
\end{equation}
includes a labeled equation and a reference to that equation. Note
that references can come before the corresponding formula as well as
after them. See the equation numbering links in the `MathJax examples
page <http://cdn.mathjax.org/mathjax/latest/test/examples.html>`_ for
more examples.
You can configure the way that numbers are displayed and how the
references to them are made using paramters in the ``equationNumbers``
block of your ``TeX`` configuration. See the :ref:`TeX configuration
options <configure-TeX>` page for more details.
