# Embedding LaTeX Math in AsciiDoc dblatex documents

You can include LaTeX math equations in AsciiDoc documents that are processed by dblatex. The AsciiDoc latexmath macros and passthrough blocks generate DocBook inlineequation, informalequation and equation elements containing the LaTeX markup which is processed by dblatex.

## Inline equations

This markup:

    An inline equation latexmath:[$C = \alpha + \beta Y^{\gamma} + \epsilon$]
    using the 'latexmath' inline macro.

Renders:

An inline equation $C = \alpha + \beta Y^{\gamma} + \epsilon$

using the latexmath inline macro.

## Informal equations

Informal (untitled) equations are generated with a latexmath style passthrough delimited block. This markup:

    [latexmath]
    ++++++++++++++++++++++++++++++++++++++++++++
    \[C = \alpha + \beta Y^{\gamma} + \epsilon\]
    ++++++++++++++++++++++++++++++++++++++++++++

Renders:

\[C = \alpha + \beta Y^{\gamma} + \epsilon\]

Functionally identical block macro syntax:

    latexmath::[\[C = \alpha + \beta Y^{\gamma} + \epsilon\]]

Renders:

\[C = \alpha + \beta Y^{\gamma} + \epsilon\]

## Formal equations

Formal equations are titled and are generated with a latexmath style passthrough delimited block.

This markup:

    .First equation
    [latexmath]
    ++++++++++++++++++++++++++++++++++++++++++++
    \[C = \alpha + \beta Y^{\gamma} + \epsilon\]
    ++++++++++++++++++++++++++++++++++++++++++++

Renders:

      & \sin \theta \sin \psi

      & - & \sin \varphi \sin \psi + \cos \theta \cos \varphi \cos \psi\\
      \end{array}
    \right] \]
