## Chapter 25. Mathematical Formulas

The *asciimath* and *latexmath* passthrough macros along with
*asciimath* and *latexmath* passthrough blocks provide a
(backend dependent) mechanism for rendering mathematical formulas. You
can use the following math markups:

The *latexmath* macro used to include *LaTeX Math* in DocBook
outputs is not the same as the *latexmath* macro used to include
*LaTeX MathML* in XHTML outputs. *LaTeX Math* applies to DocBook
outputs that are processed by dblatex and is normally used to
generate PDF files. *LaTeXMathML* is very much a subset of *LaTeX
Math* and applies to XHTML documents. |

LaTeX
math can be included in documents that are processed by
dblatex(1). Example inline formula:

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

For more examples see the AsciiDoc website or the
distributed `doc/latexmath.txt`

file.

ASCIIMathML
formulas can be included in XHTML documents generated using the
*xhtml11* and *html5* backends. To enable ASCIIMathML support you must
define the *asciimath* attribute, for example using the `-a asciimath`

command-line option. Example inline formula:

asciimath:[`x/x={(1,if x!=0),(text{undefined},if x=0):}`]

For more examples see the AsciiDoc website or the
distributed `doc/asciimathml.txt`

file.

*LaTeXMathML* allows LaTeX Math style formulas to be included in XHTML
documents generated using the AsciiDoc *xhtml11* and *html5* backends.
AsciiDoc uses the
original
LaTeXMathML by Douglas Woodall. *LaTeXMathML* is derived from
ASCIIMathML and is for users who are more familiar with or prefer
using LaTeX math formulas (it recognizes a subset of LaTeX Math, the
differences are documented on the *LaTeXMathML* web page). To enable
LaTeXMathML support you must define the *latexmath* attribute, for
example using the `-a latexmath`

command-line option. Example inline
formula:

latexmath:[$\sum_{n=1}^\infty \frac{1}{2^n}$]

For more examples see the AsciiDoc website or the
distributed `doc/latexmathml.txt`

file.

MathML is a low level XML markup for
mathematics. AsciiDoc has no macros for MathML but users familiar with
this markup could use passthrough macros and passthrough blocks to
include MathML in output documents.
