Text Formatting ⇒ How to have Italic AND bold, in math mode ?

[Cham]

I need to write some math symbols in italics AND bold. Currently, I can't have both styles at the same time. Is there a way ?

EDIT : I've found a solution, but I'm not sure it's a "proper" one :

I added this macro to my preambule :

Code: Select all

\newcommand{\qvec}[1]{\textbf{\textit{#1}}}

Then when I type \qvec{F} for example, I get a bold with italics F.

Is there a better way to do this ?

Yes, you could load the amsmath package and use the command \boldsymbol{...}.

Ahaa ! Thanks ! This one gives a better output. So I'll modify my macro. Thanks again.

A stupid question :

Do you think the scalar product of vectors should be in bold ? I mean, should we use \cdot, or \boldsymbol \cdot instead ? (or something like \sdot defined as a macro)

I've seen the normal \cdot. Check

to see the common use, the dot is usually not bold.
