\boldmath must be used outside of math

that is the default

set it correct. See example

Problem 1: Using boldface in math mode.
The problem: I want the math symbol $\symbf{B_{3}}$ to be in boldface in 
math mode with $B$ not
upright. Both B and its subscript 3 should be in boldface.


This is the original in plain math.

$B_3\big(s,a,(a+4)/3\big)$

\verb"$B_3\big(s,a,(a+4)/3\big)$"


\boldmath${B_3}\big(s,a,(a+4)/3\big)$

\verb"\boldmath${B_3}\big(s,a,(a+4)/3\big)$"

Typeface issues.

Problem 2: The emphasis and italic typeface commands produce identical 
output.
Examples follow.

These illustrate the issue with \verb"\emph".

\emph{Emphasis},  \textit{\emph{Emphasis} in italic mode}

\textit{Italic}, \emph{\textit{Italic} in emphasis mode}
