 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|{{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}}

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={{sfrac|∂² ''f''|∂''r''²}} + {{sfrac
|∂''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 ('|').

In contrast, there is

<math display=block>\frac{\part^2 f}{\part r^2} + \frac{\part f}{\part r} = 0</math>

which produces

$${\frac {\partial ^{2}f}{\partial r^{2}}}+{\frac {\partial f}{\partial r}}=0.$$

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.
