## Edutopia 2 years ago In reference to integrals: ive seen this on a site " ò(math stuff)dx, does anyone know what the " ò" symbol is denoting? there was not an integral sign anywhere.

1. AccessDenied

Is that the exact character used, or just looks something like that?

2. AccessDenied

Or did it look something like: $$\partial$$ ?

3. Edutopia

copy and pasted it was ò

Hmm... http://puu.sh/1W0B0 Are you seeing this like I am? (Ignore the highlights, but I see that the integral is highlighted with my search for "ò")

6. AccessDenied

Ohh, I think I see what it is. ,, <span style="mso-char-type:symbol;mso-symbol-font-family:Symbol">ò</span> ,,

7. Edutopia

interesting... I was thinking it might be analogous for the integral sign?

8. Edutopia

what is it?

9. AccessDenied

it appears that they are using a particular font that changes the ò into an integral sign. I believe what is happening is that you do not have this font typeface (called "Symbol"), so it is not actually displaying it as the author intended.

ah, wonderful, thank you for your insight. It seems i thought i stumbled upon a new notation where as it is simply my browser! lol

You're welcome. :) Yeah, I was confused since I've never seen that character in my life. It just reminded me of something I've spotted a few times while browsing Math stuff, which looks more like this: $$\partial$$, so it seemed like an integral over a boundary or something weird like that. lol

It doesn't seem like they use any other font tricks like that, so I am thinking if you just imagine each ò as an integral sign $$\int$$, you'll be good. :P
