Math & Science ⇒ Centering equations with caveat

[theo moore]

Here's an example. I'd like to type the equation

Code: Select all

\begin{equation}
x^2 + y^2 + z^2 = 1, \text{\qquad with $x,y,z \in \mathbb{Z}$}
\end{equation}

I'd like to keep the main equation centered in the page, but with the little text off to the side. The reason is that if you have a bunch of these equations down the page, it just looks nicer if the main parts are centered, rather than the equations.

You could do:

Code: Select all

\begin{equation}
x^2 + y^2 + z^2 = 1 \put(0,0){\qquad with $x,y,z \in \mathbb{Z}$}
\end{equation}

If you have several equations on the same page you want to align nicely with paragraphs in between, however, consider using the align environment with the \intertext command. See the amsmath documentation for more info.

Another solution that works with a box.

Code: Select all

\documentclass{article}
\usepackage{amsmath,amssymb}

\begin{document}
  \begin{equation}
    x^2 + y^2 + z^2 = 1 \makebox[0pt][l]{\qquad with $x,y,z \in\mathbb{Z}$}
  \end{equation}
\end{document}
