This question already has an answer here:

Is there any way to accomplish this nicely in latex:

enter image description here

See how there is a 'where' clause afterwards that specifies what all of the variables represent? Is there a nice way of typesetting that inside the mathematics block or would you just write:

\emph{where}
\begin{itemize}
    \item blah blah blah
    ...
\end{itemize}

I'm really looking for a special latex math method of doing what you see in the image above.

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

    
Do you also want the box around the formula? –  Claudio Fiandrino Feb 5 '13 at 9:25
    
I usually do it outside the math environment, with a \noindent before. –  Count Zero Feb 5 '13 at 9:27

I do it outside the math block too, usually. These definitions belong to the text, not to the equation, in my opinion. Also, there is no need for \noindent if you don't leave any blank line between the equation and the "where" statement, actually. Just type it as you would type the end of a sentence containing an equation. –  T. Verron Feb 5 '13 at 9:30
    
@ClaudioFiandrino There is no need for the box typesetting. I am just concerned with the 'where' section that defines what the variables mean. It seems so far like everybody just writes it straight into the text but I'll leave this question open to see if somebody does this in a clever or different way. Thanks for the comments so far. –  Robert Massaioli Feb 5 '13 at 9:34
    
I would do it as T.Verron does. I was hoping that we could use the the new norndcorners feature of @ClaudioFiandrino's hf-tikz package here. :-) –  hpesoj626 Feb 5 '13 at 9:40

You can make your own where environment that automates this process:

\documentclass{article}
\newenvironment{where}{\noindent{}where\begin{itemize}}{\end{itemize}}

\begin{document}
\begin{where}
  \item Statement 1
  \item Statement 2
  \item Statement 3
\end{where}
\end{document}
