# Centering an equation vertically

I would like to put an equation at the center of a page in beamer (viewing the page from top to bottom rather than left to right - I already know how to center an equation going from left to right). I would also like to have some text above the equation. How can I do both at once?

So you want the text to appear just below the \frametitle, and then the equation is vertically centred on the slide? The simple frame: \begin{frame} \frametitle{Frame title} Here is some text $f(x) = ax^2 + bx + c$ \end{frame} produces a centred equation and text immediately above it. –  Werner Sep 26 '12 at 19:18

beamer frames are vertically centered by default unless you have \documentclass[t]{beamer} or \begin{frame}[t].
You can use \vfil and \vfill to accomplish a vertically centered equation and some text that is vertically centered between the top and the equation.

## Code

\documentclass{beamer}
%\usepackage{lua-visual-debug} % used to show output debug
\begin{document}
\begin{frame}{Title}
Text over equation
\vfill
$$equatio^n$$
\vfill
\end{frame}
\end{document}


## Output

Is this what you want?
