The following TeX code is used for the examples below:

% \f is defined as #1f(#2) using the macro
\f\relax{x} = \int_{-\infty}^\infty
    \f\hat\xi\,e^{2 \pi i \xi x}
    \,d\xi

^{The code above is rendered by "}^{Prism Syntax Highlighter for Confluence}^{" which supports highlighting LaTeX syntax.}

Inline rendering

You can include math expressions like

% \f is defined as #1f(#2) using the macro
\f\relax{x} = \int_{-\infty}^\infty
    \f\hat\xi\,e^{2 \pi i \xi x}
    \,d\xi

(inline) within your regular Confluence content.

Block rendering

You can also include the math expression

% \f is defined as #1f(#2) using the macro
\f\relax{x} = \int_{-\infty}^\infty
    \f\hat\xi\,e^{2 \pi i \xi x}
    \,d\xi

as block element on your Confluence page.
