If you want to have the symbols  aligned you can use the command & :
If you don't want  and  to be aligned on the left, you'll have to use an array instead of the cases environment : |

| |  Arc symbol
What do you use for the arc symbol? I've been using
\widehat{ABC} to get  , but that's not quite it.
I tried using: \stackrel{\frown}{ABC} 
That just doesn't look right, either. It's too small.

One can define this command...but you can't do so here on MHF. If you had a LaTeX editor [like TeXnic Center], you can post the following into the preamble of the document: Code: \newcommand{\diam}[1]{\text{diam}\left(#1\right)}
And then when you type \diam E, it gives you
