[help-texinfo] Bold and italized font in math mode

[Fritz Jetzek]

Hi everyone,
        
        sorry to pose a seemingly trivial question to this list:
        
        Is there a way to use bold and italized fonts in texinfo @math
        mode (or
        in @tex environments)?
        I have used various combinations of \bf and \it etc. but got
        only either
        bold or italized fonts.
        
        Thanks for any suggestion, and please CC me as I'm not on the
        list.
        
        Fritz
