I want to be able to make several symbols bold by grouping them within some sort of bolding command. I can make a single symbol bold by using (for example)
\boldsymbol \phi
but I want to be able to bold several symbols, something like:
{\boldsymbol \phi \vee \psi}
This doesn't work. I've tried \bf
in a group as well, which Mathjax says it supports, but it doesn't.
How can I achieve this, I don't want to have to put \boldsymbol
on every single symbol!
Use
\boldsymbol{\phi \vee \psi}
. Note that\boldsymbol
is a macro that takes an argument (like\mathbf{}
), not a switch (like\bf
). Also, note that in TeX,\bf
only affects certain symbols (basically, just the letters and numbers), and MathJax does the same. So in TeX, as well as MathJax,{\bf \phi \vee \psi}
will produce the same thing as\phi \vee \psi
.
