Template: Oiint/doc

This template is used to include the double 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

Two of Maxwell's equations, e.g. the Maxwell–Faraday equation and Ampère's circuital law (with Maxwell's addition).
