I normally use the equation editor in Microsoft Word to generate equations to be included in Word documents.
Is there a simple way to include such an equation into a post here?

See here for details of Word's \$\LaTeX\$ math mode capabilities in the equation editor. There's an embedded video on how to get \$\LaTeX\$ out of the equation editor.
Anybody got a syringe I can use to squeeze the magic smoke back into this?

OpenOffice.org/LibreOffice/... users can use the Math editor and export to MathML when using "Save As". From there you can choose a number of options.

For those using wxMaxima, you can select any expression, right click and use "Copy as LaTeX". Then paste.

\[\frac{\cos{(x)}}{x}-\frac{\sin{(x)}}{{{x}^{2}}}\]

Note that it won't be displayed WYSIWYG in preview mode, which is annoying.

(MathJax == LaTex like syntax)
The best brief MathJax tutorial:
https://math.meta.stackexchange.com/questions/5020/mathjax-basic-tutorial-and-quick-reference




Random demo from the above link examples:
Code: [Select]
\$\require{AMScd} \require{cancel}\$
\begin{CD}
    A @>a>> \mathrm{ \color{red}{AC \unicode{x21af} DC} \impliedby \overline{ \xcancel{not} ITALIC} }\\
    @V b V V{f(n) =
        \begin{cases}
            \sum_{i=1}^n i^2 = \frac{n(n+1)(2n+1)}{6},  & \text{if $n$ is even} \\[2ex]
            3n+1, & \text{if $n$ is odd}
        \end{cases}}
    @VV c V\\
    e^{i\pi/2} @>>d> {\mu_0=4\pi\times10^{-7} \ \left.\mathrm{\mathrm{T}\!\cdot\!\mathrm{m}}\middle/\mathrm{A}\right.}
\end{CD}

\$\require{AMScd} \require{cancel}\$
\begin{CD}
    A @>a>> \mathrm{ \color{red}{AC \unicode{x21af} DC} \impliedby \overline{ \xcancel{not} ITALIC} }\\
    @V b V V{f(n) =
        \begin{cases}
            \sum_{i=1}^n i^2 = \frac{n(n+1)(2n+1)}{6},  & \text{if $n$ is even} \\[2ex]
            3n+1, & \text{if $n$ is odd}
        \end{cases}}
    @VV c V\\
    e^{i\pi/2} @>>d> {\mu_0=4\pi\times10^{-7} \ \left.\mathrm{\mathrm{T}\!\cdot\!\mathrm{m}}\middle/\mathrm{A}\right.}
\end{CD}

Code: [Select]
\[ \star \ \star \ \star \]
Normal  \$ \unicode{x23fb} \ \unicode{x238d} \ \unicode{x23da} \ \unicode{x23fc} \ \$ text.

\[ \star \ \star \ \star \]
Normal  \$ \unicode{x23fb} \ \unicode{x238d} \ \unicode{x23da} \ \unicode{x23fc} \ \$ text.

test \$\sqrt[\pi]{\pi^\pi}=\pi\$
