===== 在 dokuwiki 中使用数学公式 =====

这里使用了[[https://www.dokuwiki.org/plugin:mathjax|插件]]

==== Inline Math ====

使用 ''$'' 符号

$a^2 + b^2 = c^2$
<code>
$a^2 + b^2 = c^2$
</code>

或 ''\('', ''\)'' 转义

\(1+2+\dots+n=\frac{n(n+1)}{2}\)  
<code>
\(1+2+\dots+n=\frac{n(n+1)}{2}\)  
</code>

==== Display Math ====

使用 ''$$'' 符号, 在单独的行显示数学公式

$$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$

<code>
$$ \frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x) $$
</code>

或使用 ''\['' , ''\]'' 转义
 
\[ \sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right] \]

<code>
\[ \sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right] \]
</code>

A wide range of math environments((Accepted math environments (specified [[https://github.com/liffiton/dokuwiki-plugin-mathjax/blob/master/syntax/protecttex.php#L27|here]] in the code): align, align*, alignat, alignat*, displaymath, eqnarray, eqnarray*, equation, equation*, flalign, flalign*, gather, gather*, math, multline, multline*)) will work as well:

\begin{align*}
e^x & = 1 + x + \frac{x^2}{2} + \frac{x^3}{6} + \cdots \\
    & = \sum_{n\geq 0} \frac{x^n}{n!}
\end{align*}

  \begin{align*}
  e^x & = 1 + x + \frac{x^2}{2} + \frac{x^3}{6} + \cdots \\
      & = \sum_{n\geq 0} \frac{x^n}{n!}
  \end{align*}



Note that the math environments //should not// be inside the dollar sign delimiters; the environments should stand on their own with just the ''\begin'' and ''\end'' statements in order to be parsed correctly.
