I know that \oint gives a closed line integral sign, but how do you make the same with a double integral instead? I tried \ooint and \oiint but neither worked.

EDIT: Also what would the corresponding commands for triple integrals be? And is there a way to do higher-order integrals (4,5,...)? Cheers!

From esint.

\documentclass{article}
\usepackage{esint}
\begin{document}
  \[
  \oiint x
  \]
  \[
  \varoiint x
  \]
\end{document}

enter image description here

\documentclass{article}
\usepackage{pxfonts}  %% or txfonts  or mathabx
\begin{document}
  \[
  \oiint x
  \]
  \[
  \oiiint x
  \]
\end{document}

enter image description here

\documentclass{article}
\usepackage[garamond]{mathdesign}  
\begin{document}
  \[
  \oiint x
  \]
  \[
  \oiiint x
  \]
\end{document}
  • Thank you! Is there anything for triple integrals? I don't really need higher than that. – user51108 May 05 '14 at 00:38
  • @user51108 I have added few possibilities. –  May 05 '14 at 01:07
  • Ah how do I decide!?!? And will that change what my integrals look like? And I tried finding these on dexterify but it didn't work, how do you find them (or do you just know cause you know this stuff)? – user51108 May 05 '14 at 01:08
  • @user51108 You can search in: http://ctan.imsc.res.in/info/symbols/comprehensive/symbols-a4.pdf . The fonts will certainly change many things. You should be cautious. –  May 05 '14 at 01:09
  • If you want to use only one symbol, then search in this site. There are answers that explain how to use only one (or more) symbol(s) without loading the full package. –  May 05 '14 at 01:13
