I have at the moment

by

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{subequations}
  \begin{equation}
    \omega_c = \sqrt{\omega_{0}^{2} - \mu^{2}}, \mu < \omega_{0}, \text{ Underdamped}
  \end{equation}
  \begin{equation}
    \omega_c = \sqrt{\mu^{2} - \omega_{0}^{2}}, \mu > \omega_{0}, \text{ Overdamped}
  \end{equation}
  \begin{equation}
    \omega_c = 0, \mu > 0, \text{ Critically damped.}
  \end{equation}
\end{subequations}
\end{document}

which I do not like.

How can you have nicely tabbed text next to equations?

Best Answer

A regular align (from amsmath) will do here:

enter image description here

\documentclass{article}
\usepackage{amsmath}% http://ctan.org/pkg/amsmath
\begin{document}
\begin{subequations}
\begin{align}
  \omega_c &= \sqrt{\omega_{0}^{2} - \mu^{2}}, & \mu &< \omega_{0}, &\text{Underdamped} \\
  \omega_c &= \sqrt{\mu^{2} - \omega_{0}^{2}}, & \mu &> \omega_{0}, &\text{Overdamped} \\
  \omega_c &= 0,                               & \mu &= \omega_{0}, &\text{Critically damped}
\end{align}
\end{subequations}
\end{document}
