Test of dokuwiki mathjax plugin

Examples/Usage

(Copied from https://www.dokuwiki.org/plugin:mathjax)

NOTE that the default configuration uses \$(dollar signs) to delimit TeX formulas. This may cause trouble if you have \$ characters in any pages. The default configuration also lets you escape the dollar signs, however, by changing them to ”\$”. This should correct any problems you might have. Once the plugin is installed, you can write TeX formulas in your wiki with the following syntax (by default — all delimiters are configurable): Inline Math Use dollar signs: $a^2 + b^2 = c^2$ $a^2 + b^2 = c^2$ or escaped parentheses: $$1+2+\dots+n=\frac{n(n+1)}{2}$$ $$1+2+\dots+n=\frac{n(n+1)}{2}$$ Display Math To display math on its own line, use double dollar signs: $$\frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x)$$ $$\frac{d}{dx}\left( \int_{0}^{x} f(u)\,du\right)=f(x)$$ or escaped square brackets: $\sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right]$ $\sin A \cos B = \frac{1}{2}\left[ \sin(A-B)+\sin(A+B) \right]$ A wide range of math environments 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*}\$
