Displaying an equation in a list

Question

How could one get a displayed equation inside a list environment, say itemize, so that the equation is both centered horizontally and on the same line as the bullet, but with the bullet still on the left? Trying \item \begin{center} \( \displaystyle \int x \ dx = \frac{x^2}{2} + C \) \end{center} centers the bullet as well as the equation.

This is a somewhat frivolous question, since I don't actually want to use the answer. I personally would use \item \( \displaystyle \int x \ dx = \frac{x^2}{2} + C \) and do without the horizontal centering. But I'm currently at a conference where I've seen several beamer presentations that clearly involved something like \item \[ \int x \ dx = \frac{x^2}{2} + C \], which made me curious how one could do what I asked, if one really wanted to.

I really wasn't sure how to tag this. Please feel free to retag.

Answer 1

Would

\item ~ \hfill \( ... \) \hfill

not work? Primitive, perhaps, but effective just for the purposes of alignment.

Unless the formulae are quite long, so that each one comes close enough to the left to be closely associated with it's corresponding bullet point, I'm not sure that I would want to do this, though. Of course, this could also be solved by doing something like

\item \begin{minipage}{0.4\textwidth}\centering \( ... \) \end{minipage}

or something similar, to center the equations on a vertical axis which is closer to the bullet points.
