## bold font in latex

$$\mathbf{\mu}$$

What is used to execute latex on this website? When I type that into TeXnic center and compile it without MikTex, it is not bold on my computer.

 Mentor For some reason, latex doesn't really like making greek letters bold. A workaround I found (which is a little annoying, but at least it works) is to use something like \mbox{\boldmath${\pi}$} if in a math environment. I don't know what is used on the website.
 Mentor Use \mathbf in math mode. \mu versus \mathbf\mu $$\mu\;\mathbf\mu$$ One drawback of mathbf: Its not in italics. a versus \mathbf a $$a\;\mathbf a$$ If you have the AMS math package (\usepackage{amssymb,amsmath}), \boldsymbol puts things in bold italics. \mu versus \mathbf\mu versus \boldsymbol\mu $$\mu\;\mathbf\mu\;\boldsymbol\mu$$ a versus \mathbf a versus \boldsymbol a $$a\;\mathbf a\;\boldsymbol a$$

Whilst that seems to work on the forum, it doesn't work for me (or, it seems, for the OP) hence why I had to find a workaround. The method you list below works fine!

 Mentor I generally use \boldsymbol. Hmm, actually, I don't, at least not directly. I generally use macros for matrices and vectors, and those in turn use \boldsymbol. That way if someone tells me to use arrows for vectors I just have to change my vector macro.
 you have to use the package{bm}. Then inside math environment type Greek letters as {\bm \alpha}, {\bm \beta}, etc... usepackege{bm} then, ${\bm beta} = {\bm \ alpha} {\bf \gamma}$
 thanks...DH post was very useful!
