\oiiint

Template documentation[view] [edit] [history] [purge]

This template is used to include the triple closed integral, usually in a mathematical formula. It overcomes a limitation of the TeX rendering which cannot display this symbol without clumsy workarounds.

 Arguments

• preintegral the text or formula immediately before the integral
• intsubscpt the subscript below the integral
• integrand the text or formula immediately after the formula

All parameters are optional.

 Examples

:{{oiiint
| preintegral = <math>\frac{1}{\sqrt{2\pi}}</math>
| intsubscpt = <math>{\scriptstyle \Omega}</math>
| integrand = <math>\frac{\partial F}{\partial s} \, {\rm d}\Sigma</math>
}}

$\frac{1}{\sqrt{2\pi }}$ \oiiint$\mathrm{\Omega }$ $\frac{\partial F}{\partial s}\mathrm{d}\mathrm{\Sigma }$

 Technical details

The \oiiint command is not part of AMS-LaTeX, and thus not part of the math support that MediaWiki provides. It is available as a unicode character U+2230 ∰ <reserved-2230> but font support for this character can be lacking. For this reason, the template provides an image variant of the character.
