The default math mode font is $Math\ Italic$. This should not be
confused with ordinary \emph{Text Italic} -- notice the different spacing\,!
\verb|\mathbf| produces bold roman letters: $ \mathbf{abcABC} $.
If you wish to embolden complete formulas,
use the \verb|\boldmath| command \emph{before} going into math mode.  
This changes the default math fonts to bold. 
 
\begin{tabular}{ll}
\texttt{normal}   & $ x = 2\pi \Rightarrow x \simeq 6.28 $\\
\texttt{mathbf}   & $\mathbf{x} = 2\pi \Rightarrow \mathbf{x} \simeq 6.28 $\\
\texttt{boldmath} & {\boldmath $x = \mathbf{2}\pi \Rightarrow x 
                    \simeq{\mathbf{6.28}}              $}\\
\end{tabular}

Greek is available in upper and lower case:
$\alpha,\beta \dots \Omega$, and there are special
symbols such as $ \hbar$.
The following letters should be upright: $\upGamma, \upDelta\dots \upOmega$.
Digits in formulas $1, 2, 3\dots$ may differ from those in text: 4, 5, 6\dots

There is a calligraphic alphabet \verb|\mathcal| for upper case letters
$ \mathcal{ABCDE}\dots $, and there are letters for number sets: $\mathbb{A\dots Z} $,
which are produced using \verb|\mathbb|.
