LaTeXMathML examples
This page is a test of
LaTeXMathML.js.
The input
\$\\$\alpha + \\$\beta = \\$(\alpha + \beta).\$
produces $\$\alpha + \$\beta = \$(\alpha + \beta).$
The input
\$\lim_{x\to\infty} f(x) = k \choose r + \frac ab \sum_{n=1}^\infty a_n +
\displaystyle{ \left\{ \frac{1}{13} \sum_{n=1}^\infty b_n \right\} }.\$
produces $
\lim_{x\to\infty} f(x) = k \choose r +
\frac ab \sum_{n=1}^\infty a_n + \displaystyle{ \left\{
\frac{1}{13} \sum_{n=1}^\infty b_n \right\} }.$
Changing
\displaystyle to
\textstyle
and
\$...\$ to
<blockquote>\$\displaystyle{ ...
}\$</blockquote>
gives
$\displaystyle{
\lim_{x\to\infty} f(x) = k \choose r +
\frac ab \sum_{n=1}^\infty a_n + \textstyle{ \left\{
\frac{1}{13} \sum_{n=1}^\infty b_n \right\} }.$
The input
<blockquote>\$\begin{eqnarray}
x & = & \frac{-7 \pm \sqrt{49 - 24}}{6} \\
& = & -2 \textrm{ or } -\frac13.
\end{eqnarray}\$</blockquote>
produces
$\begin{eqnarray}
x & = & \frac{-7 \pm \sqrt{49 - 24}}{6} \\
& = & -\frac13 \textrm{ or } -2.
\end{eqnarray}$
(LaTeXMathML tries to reduce the column spacing in eqnarrays,
but some browsers do not respond, and others over-react.)
The input
<blockquote>\$\displaystyle{
f(x) := \left\{\begin{array}{l l}
x^2 \sin \frac1x & \textrm{if } x \ne 0, \\
0 & \textrm{if } x = 0 .
\end{array}\right.}\$</blockquote>
produces
$\displaystyle{
f(x) := \left\{\begin{array}{l l}
x^2 \sin \frac1x & \textrm{if } x \ne 0, \\
0 & \textrm{if } x = 0 .
\end{array}\right.
}$
The input
<blockquote>\$\displaystyle{
A = \left[\begin{array}{c c c}
1-x & 0 & 0 \\ 0 & 1-x & 0 \\ 0 & 0 & 1-x \end{array}\right].
\$</blockquote>
produces
$\displaystyle{
A = \left[\begin{array}{c c c}
1-x & 0 & 0 \\ 0 & 1-x & 0 \\ 0 & 0 & 1-x \end{array}\right].
}$
Large summation signs, etc., without limits can sometimes get too big.
For example, the input
\$\sum a_i + \sum_{i=0}^\infty b_i.\$
produces
$
\sum a_i + \sum_{i=0}^\infty b_i .
$
In some browsers,
the presence of the second summation sign, with limits, makes
the first one too big.
Enclosing the first one in braces, as in
{\sum a_i}, produces
$
{\sum a_i} + \sum_{i=0}^\infty b_i ,
$
which is arguably better.
(This is a bug in LaTeXMathML, but one that would be difficult
to correct.)
