The following parameter entities contain m: indexinline, inline

Corresponds to `$...$` in LaTeX, but uses a somewhat
different expression syntax, see below.
*Attention:* If it has
an `id`, it's becoming a *displayed* Formula, with a
number.

You can use `<m>` inside MathML's `<math>`. The same
applies to `<ch>` and `<unit>`.

In principle, you can use `<m>` wherever you can use
`<mrow>`. However, sometimes it may be necessary to enclose
`<m>` and friends with `<mrow>`, because they may expand
to multiple MathML elements.

You can use directly MathML's presentation markup in tbook files.
For this, insert `<math>` elements without worrying about
namespaces. But except for not too complicated equations this is quite
longish.

tbook's formula elements `<m>` and friends use simplified
LaTeX syntax. You may use roots, fractions, standard functions
like “$\sin$”, stretchable braces, sub- and superscripts and
accents. You may nest these structures so deep until your XSLT
processor complains. And you can use these elements *inside*
MathML to get the best of both worlds. (However HTML output only
contains valid MathML.)

Roots work with `\sqrt`, fractions with `\frac`, just as in
LaTeX. Human text is included via `\text` that is known from
AmSTeX. Standard functions are typed without a ``\`'.
Stretchable braces are all braces immediately within a `{...}`
grouping. Sub- and superscrips as in LaTeX, but always a possible
subscript *before* the superscript. Accents are just written
*immediately* before the accented variable or group, they're
made wide accents if necessary. If you make a space between accent
and anything that follows, the accent is treated as an operator.
(So, a `\vec` becomes a `\to`.)

Here an example:

<m>^{1-x_{\text{eff}}} ≠ {( ∫_0^∞ sin(˜x) \frac{\sqrt[3]{1/e}}β dx )} ≠ lim_{x → ∞}\frac1x</m>

becomes

For HTML output, the responsible stylesheet produces:

<math><mover accent="true"><mrow><mn>1</mn><mo>-</mo><msub><mi>x</mi> <mrow><mtext>eff</mtext></mrow></msub></mrow> <mo>^</mo></mover><mo>≠</mo><mrow><mo>(</mo> <munderover><mo>∫</mo><mn>0</mn><mo>∞</mo></munderover> <mi>sin</mi><mo stretchy="false">(</mo><mover accent="true"> <mi>x</mi><mo>~</mo></mover><mo stretchy="false">)</mo> <mfrac><mrow><mroot><mrow><mn>1</mn><mo>/</mo><mi>e</mi></mrow> <mn>3</mn></mroot></mrow><mi>&beta</mi></mfrac><mi>d</mi><mi>x</mi> <mo>)</mo></mrow><mo>≠</mo><munder><mi>lim</mi><mrow><mi>x</mi> <mo>→</mo><mo>∞</mo></mrow></munder><mfrac><mn>1</mn> <mi>x</mi></mfrac></math>

Lucky us.

Notice that you can use `<m>`, `<ch>` and `<unit>`
*within* MathML constructs. If you use these elements within a
MathML equation *array*, you can generate alignment markers (in
LaTeX known as ``&`' signs) with ``#`' signs, because
this is shorter than `&`. Put them where they would be in
LaTeX. Although MathML requires such a marker at the very beginning
of an equation row, this is not true for LaTeX, and not true for
tbook.

In this context some words about MathML. You may use it if you
want, for more complicated formulas you must use it, unfortunately.
It's always enclosed by `<math>...</math>`, but
only presentation markup can be transformed to LaTeX yet.

tbook treats a `<math>` element as an equation array, if it
consists of only *one* `<mtable>`, with a `groupalign`
attribute *or* one or more `<mlabledtr>` rows. If you set
`groupalign="right center left"`, this leads to
an `eqnarray` in LaTeX, and where ``&`' are in LaTeX, you
have to use `<maligngroup/>` in MathML. Else the equations are
just stacked and not aligned. But as already mentioned, you can also
use `<m>` inside `<math>`, which is very helpful for
equation arrays:

<math> <mtable groupalign="right center left"> <mtr> <mtd id="test"> <m> 1+1 #=# 2 </m> </mtd> <mtd> <m> 4 #=# 2 · 2 </m> </mtd> </mtr> </mtable> </math>

which is the same as LaTeX's

\begin{eqnarray} 1+1 &=& 2 \label{Test} \\ 4 &=& 2 \cdot 2 \nonumber \\ \end{eqnarray}

and you don't want to see the HTML/MathML output tbook must create
for that. By the way, being the only child element of an
`<mtd>`, `<m>` is implicitly surrounded by an `<mrow>`
which is necessary in this context.

A tricky point is equation labelling and numbering. tbook supports three ways of giving an equation a label:

- A
`<math>`element has an`id`attribute. Plain and simple. - An
`<mtd>`element with an`id`within an equation array (see above). - An
`<mlabledtr>`element with an`id`within an equation array, and the contents of the first`<mtd>`element of such an`<mlabeledtr>`row.

You may use the `<ref>` element to refer to such equations, but
for the contents of the `<mtd>` element in the third case, you
have to use `<mathref>`. I would recommend you to use only 1.
and 2. See the MathML specs at the W3C for more information.
