MathJax command - Double-triple integral

AI Thread Summary
The discussion focuses on finding MathJax commands for double and triple integrals, specifically for surface integrals of closed surfaces. Users mention that the commands \oiint and \oiiint are expected to produce the desired results but report that these commands are not supported in MathJax. Alternative Unicode symbols for integrals, such as \unicode{x222F} and \unicode{x2230}, are provided but may not meet the user's needs. The thread references a related question on TeX Stack Exchange for further assistance. Overall, the search for proper MathJax support for these integral commands remains unresolved.

I've been trying to find the commands for a surface integral of a closed surface,

Doing some searches, I've found that \oiint \oiiint are supposed to give the desired result, but they don't seem to be supported!

I want to thank those members who interacted with me a couple of years ago in two Optics Forum threads. They were @Drakkith, @hutchphd, @Gleb1964, and @KAHR-Alpha. I had something I wanted the scientific community to know and slipped a new idea in against the rules. Thank you also to @berkeman for suggesting paths to meet with academia. Anyway, I finally got a paper on the same matter as discussed in those forum threads, the fat lens model, got it peer-reviewed, and IJRAP...
About 20 years ago, in my mid-30s (and with a BA in economics and a master's in business), I started taking night classes in physics hoping to eventually earn the science degree I'd always wanted but never pursued. I found physics forums and used it to ask questions I was unable to get answered from my textbooks or class lectures. Unfortunately, work and life got in the way and I never got further the freshman courses. Well, here it is 20 years later. I'm in my mid-50s now, and in a...
