# How to make the equation very extended bold?

How could choose the level of boldness?

The difficult point is that it is not bold the text.

Any idea?

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

\begin{document}

\boldmath\boldmath\boldmath{\boldmath
\fbox{
\begin{minipage}[c]{\textwidth}%
$\bullet$ Initialization: $x^0 \in X$, $\lambda \in R$

$\bullet$ Iterations $n\ge 0$: Update $\tau^n$, $\widehat{x}^n$ and $x^n$ as follows
$$x=y$$
\end{minipage}
}}
\end{document}

• $\pmb{\pmb{\bm{a^2+b^2=c^2}}}$ with \usepackage{amsmath,bm}, but Please, don't do that! (Because every time someone uses \pmb, Gutenberg kills a kitten.) – yo' Dec 2 '13 at 19:31
• Hi, thank you. But found it do not work for $$\pmb{\pmb{\bm{a^2+b^2=c^2}}}$$ – Vivian Dec 2 '13 at 19:42
• Can you add a little mor information, maybe in form of a minimal working example? @tohecz :-) – Johannes_B Dec 2 '13 at 19:44
• Is it something like this? If not, please be a bit more specific. \documentclass{article} \usepackage{amsmath,bm} \let\origtextbf\textbf \renewcommand\textbf[1]{\mathversion{bold}\origtextbf{#1}\mathversion{normal}} \begin{document} { \fbox{ \begin{minipage}[c]{\textwidth}% \begin{itemize} \item Initialization: $x^0 \in X$, $\lambda \in R$ \item \textbf{Iterations $n\ge 0$: Update $\tau^n$, $\widehat{x}^n$ and $x^n$ as follows} \end{itemize} $$x=y$$ \end{minipage} }} \end{document} Code taken from matheplanet.com/default3.html?call=viewtopic.php?topic=188829 – Johannes_B Dec 2 '13 at 20:08

# I. Poor man's solution that should never be used

As I said in the comments, you can use so-called "poor-man's bold", even twice. However, the result is so bad that every time you use it, Gutenberg kills a kitten.

\documentclass{article}

\usepackage{amsmath,bm}

\begin{document}

Pythagoras' formula:
$\pmb{\pmb{\bm{a^2+b^2=c^2}}}$

\end{document}


# II. What to do instead

You can just use \bm or \boldmath (see How to make all math equations bold by default for more details on \boldmath).

Additionally, you can switch to a font that distinguishes bold from non-bold better than Computer Modern or Latin Modern does, for example New Century Schoolbook, loaded through \usepackage{fouriernc} (remember to load bm after all other font packages):

\documentclass{article}

\usepackage{fouriernc}
\usepackage[T1]{fontenc}
\usepackage{bm}

\begin{document}

\noindent
Pythagoras' formula:
\\
$\bm{a^2+b^2=c^2}$
\\
$a^2+b^2=c^2$

\end{document}
