=== 用法 ===
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.

=== 示例 ===
* <code><nowiki>
{{bigmath|{{frac|&part;&sup2;<VAR >f</VAR >|&part;<VAR >r</VAR >&sup2;}} + {{frac|&part;<VAR >f</VAR >|<VAR >r</VAR > &part;<VAR >r</VAR >}} + {{frac|&part;&sup2;<VAR >f</VAR >|<VAR >r</VAR >&sup2;&part;&sup2;<VAR >&theta;</VAR >}} {{=}} 0}}
</nowiki> </code>
produces:

* {{bigmath|{{frac|∂²<VAR >f</VAR >|∂<VAR >r</VAR >²}} + {{frac|∂<VAR >f</VAR >|<VAR >r</VAR > ∂<VAR >r</VAR >}} + {{frac|∂²<VAR >f</VAR >|<VAR >r</VAR >²∂²<VAR >θ</VAR >}} {{=}} 0}}

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

* {{bigmath|1={{frac|∂² ''f''|∂''r''²}} + {{frac
|∂''f''|''r'' ∂''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 ('|').

=== Performance considerations ===
Template {<nowiki/>{bigmath}} can process formulae (or equations) at rates over 220 per second. When template {{[[Template:frac|frac]]}} is also used, the rate drops to below 150 equations formatted per second.
