    \[ \oint ? \] It'd be \oint

    No, most people make it: \[ \oint\oint \]There's no standard LaTeX way to do it, you need a package called wasysym, that makes it: \oiint

    How can I invoke packages here? I tried using \usepackage{wasysym}, but it does not work.

    No, you cannot do it on here, since I don't think the \(\LaTeX\) compiler parses it.

    Simply do something like: \[ \underbrace{\oint\oint}_\textrm{Surface} \]\underbrace{\oint\oint}_\textrm{Surface} You're kind of limited in this case... but you could add this to the Feedback Page.

    This is the best hack-and-slash approach I could find:\[\iint_S\!\!\!\!\!\!\!\!\!\!\!\!\!\!\;\;\;\bigcirc\]But it sucks.

    I always tend to find symbols by \(\textbf{drawing}\) them: http://detexify.kirelabs.org/classify.html
