Usage

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.

Examples

• {{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}}

produces:

• ^∂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:

• ^{∂² f}⁄_∂r² + ^∂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 {{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.
