Thread: double integral sign

hi i need to enter in a symbol which is a double integral sign with a circle through both and an S down the bottom. similar to but with 2 integral signs and the o goes between both signs. does this make sense?

There are special LaTeX packages in which you can use those. However, I don't believe we have them installed at the forums.

By the way, doesn't that type of integral represent a volume integral?

correct. it is part of a question about a cube and its surface bounded by planes. ill try again to insert the question into the post.

Here is a cheat:

[tex]\bigcirc \hspace{-1.4em} \int \hspace{-.8em} \int [/tex] gives

thanks heaps do you know how i add the S down the bottom ie. it looks like a bottom limit?

Here's a thread I just found that's got stuff better than mine: http://www.mathhelpforum.com/math-he...-integral.html

Standard subscript:

[tex]\bigcirc \hspace{-1.4em} \int \hspace{-.8em} \int_S [/tex]

Like this:

The code is [tex]\bigcirc \hspace{-1.4em} \int \hspace{-.8em} \int\limits_{S} [/tex]

You could probably add the \limits_{S} bit to the code in the thread I previously referenced.


Edit: I just saw that CaptainB provided the more obvious and simpler alternative. So it's really just a matter of where you like your S to be. I assumed you'd tried that and (like Chris, who showed me the \limits command a while ago) didn't like it ......
