SDIY wiki supports embedding mathematical formulas using <code><nowiki><
<m>\operatorname{erfc}(x) = \frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt = \frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}}</m>
===Alternately (beta)===
Use <code><nowiki><math></nowiki></code> tags, [http://en.wikipedia.org/wiki/TeX TeX] or [https://en.wikipedia.org/wiki/LaTeX LaTeX] notation, [https://en.wikipedia.org/wiki/MathML MathML], or [https://en.wikipedia.org/wiki/ASCIIMathML AsciiMath] notation.

We consider, for various values of $s$, the $n$-dimensional integral
\begin{align}
Line 24 ⟶ 26:
W_3(k) &= \Re \, \pFq32{\frac12, -\frac k2, -\frac k2}{1, 1}{4}.
\end{align}
Appropriately defined, \eqref{eq:W3k} also holds for negative odd integers. The reason for \eqref{eq:W3k} was long a mystery, but it will be explained at the end of the paper.
