用法

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

示例

{{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}}

produces:

$.mw-parser-output .frac{white-space:nowrap}.mw-parser-output .frac .num,.mw-parser-output .frac .den{font-size:80%;line-height:0;vertical-align:super}.mw-parser-output .frac .den{vertical-align:sub}.mw-parser-output .sr-only{border:0;clip:rect(0,0,0,0);clip-path:polygon(0px 0px,0px 0px,0px 0px);height:1px;margin:-1px;overflow:hidden;padding:0;position:absolute;width:1px}∂²f⁄∂r² + ∂f⁄r ∂r + ∂²f⁄r²∂²θ = 0$

Use prefix "1=" to allow simple equals-signs. Italicize letters by double-tic (''f''):

{{bigmath|1={{frac|∂² ''f''|∂''r''²}} + {{frac |∂''f''|''r'' ∂''r''}} = 0}}

produces:

$\partial² f ⁄ \partial r ² + \partial f ⁄ r \partial r = 0$

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 {{bigmath}} can process formulae (or equations) at rates over 220 per second. When template {{frac}} is also used, the rate drops to below 150 equations formatted per second.
