I'm typing a bold vector small x with a tilde sign above it. Now when I want to write its derivative, I'm putting a dot on top of everything. This is giving me problems and I found one solution:
\overset{\mathrm{\textbf .}}{\boldsymbol{\mathrm{\tilde{x}}}}
after I read this post: How to make a larger "\dot" .
This post has a solution for a similar problem: \overset{\bm .}{a}
To write bold mathematical symbols, such as vectors is \boldsymbol
better or do you recommend using the bm
package? I have always been using \boldsymbol
.

If you take a look at the documentation for
bm
, it says that if the bold fonts are not allocated, it will use the correct symbol—if it exists—by using\boldmath
, but that this is slower. If there is not a bold version of the symbol, it uses poor man's bold.I think that in most cases, you want to use
\bm
.
