Is there any way to accomplish this nicely in latex:

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.

Just type it as you would type the end of a sentence containing an equation. – T.
