Load the bm package in your preamble. Do this after all packages, which define symbol fonts. If you are not sure about this, place this line below all font packages:
|
1 2 |
\usepackage{bm} |
Declare a command for each bold symbol:
|
1 2 3 |
\bmdefine{\balpha}{\alpha} \bmdefine{\bX}{X} |
Use the new macros in your document within math mode.
