Nýtsla

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.

Dømi

{{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:

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

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.
