Template:Bigmath/doc

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

Using the following code as the variable N

{{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>}}

...in the {{math}} template, e.g. {{math| N {{=}} 0}}, produces:

⁠∂²f/∂r²⁠ + ⁠∂f/r ∂r⁠ + ⁠∂²f/r²∂²θ⁠ = 0

...in the {{bigmath}} template, e.g. {{bigmath| N {{=}} 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.
