What's the TeX for a double closed loop integral?

Homework Statement

I tried using \ooiint, I want a loop that circles both integrals (two), anyone know?

I don't know if you can do it without including an extra package called wasysym in your LaTeX source file. I did some searching and found that if you put \usepackage{wasysym} in your document preamble, a control sequence called \oiint becomes available. I've attached a pic of what it looks like. Next time try Googling for it yourself. It wasn't too long before I found an online PDF called "The Comprehensive LaTeX Symbol List" with this information in it.

Actually, I kind of like the ones in the package esint instead. It includes \oiint and \varoiint (attached in that order).

I'm not sure if there's any way to enable these on PF, if that's your question. You could ask in Forum Feedback.
