Why is it that when I type the following:
$\mathbf{\mu}$
the mu is not bolded?
Consider this code:
\documentclass[12pt]{article}
\usepackage{amsmath}
\usepackage{graphicx}
\usepackage{pdfpages}
\title{Test}
\author{Test}
\date{}
\begin{document}
\maketitle
$\mathbf{\mu}$
\end{document}
The mu is not bolded. I am using TeXWorks.
\usepackage{bm}and$\bm{\mu}$. See also http://tex.stackexchange.com/q/595/35864. – moewe Sep 11 '13 at 17:14
