=== Usage ===
Use this template to embed stand-alone formulae in wikitext.  The mathematical capabilities of this template are very limited; use tables with <code>class="texhtml"</code> for formulae requiring non-linear layout.

=== Examples ===

==== Using the following code as the variable '''{{mono|{{var|N}}}}''' ====
<syntaxhighlight lang="wikitext">
{{sfrac|&part;&sup2;<var>f</var>|&part;<var>r</var>&sup2;}} + {{sfrac|&part;<var>f</var>|<var>r</var> &part;<var>r</var>}} + {{sfrac|&part;&sup2;<var>f</var>|<var>r</var>&sup2;&part;&sup2;<var>&theta;</var>}}
</syntaxhighlight>

:...in the <syntaxhighlight lang="wikitext" inline>{{math}}</syntaxhighlight> template, e.g. '''<syntaxhighlight lang="wikitext" inline>{{math| N {{=}} 0}}</syntaxhighlight>''', produces:
:: {{math|{{sfrac|&part;&sup2;<var>f</var>|&part;<var>r</var>&sup2;}} + {{sfrac|&part;<var>f</var>|<var>r</var> &part;<var>r</var>}} + {{sfrac|&part;&sup2;<var>f</var>|<var>r</var>&sup2;&part;&sup2;<var>&theta;</var>}} {{=}} 0}}
:...in the <syntaxhighlight lang="wikitext" inline>{{bigmath}}</syntaxhighlight> template, e.g. '''<syntaxhighlight lang="wikitext" inline>{{bigmath| N {{=}} 0}}</syntaxhighlight>''', produces:
:: {{bigmath|{{sfrac|&part;&sup2;<var>f</var>|&part;<var>r</var>&sup2;}} + {{sfrac|&part;<var>f</var>|<var>r</var> &part;<var>r</var>}} + {{sfrac|&part;&sup2;<var>f</var>|<var>r</var>&sup2;&part;&sup2;<var>&theta;</var>}} {{=}} 0}}

==== Use prefix "1=" to allow simple equals-signs ====
Italicize letters by double-tic (<code><nowiki>''f''</nowiki></code>):
<syntaxhighlight lang="wikitext">
{{bigmath|1={{sfrac|&part;&sup2; ''f''|&part;''r''&sup2;}} + {{sfrac|&part;''f''|''r'' &part;''r''}} = 0}}
</syntaxhighlight>

:...produces:
::{{bigmath|1={{sfrac|&part;&sup2; ''f''|&part;''r''&sup2;}} + {{sfrac|&part;''f''|''r'' &part;''r''}} = 0}}
:Note that any extra spaces placed in the template will appear in the output. A long line can be split before any vertical-bar pipe ('|').

In contrast, there is <syntaxhighlight lang="tex" inline><math display=block>\frac{\part^2 f}{\part r^2} + \frac{\part f}{\part r} = 0</math></syntaxhighlight> which produces:

<math forcemathmode=mathml display=block>\frac{\partial^2 f}{\partial r^2} + \frac{\partial f}{\partial r} = 0.</math>

This might be an alternative for more complex examples. If that's still too small, leave a comment on https://phabricator.wikimedia.org/T135419 please.
