Boldface Sigma LaTeX Problem

  1. Nov 14, 2008 #1
    1. The problem statement, all variables and given/known data
    I am trying to write a paper describing my undergraduate research and its progress to a committee. I am having trouble making my sigmas boldface using LaTeX. I am using the correct coding, because it is working when I wish to type other vectors, but the sigmas look the same whether I type \mathbf{\sigma} or {\bf \sigma}. My temporary fix is to just put an arrow above with \vec{\sigma}, but I don't want to be inconsistent with my other vectors being boldface. What can I do to make the boldface of my sigmas more noticeable?

    2. Relevant equations

    \mathbf{\sigma} or {\bf \sigma}?

    3. The attempt at a solution

    i guess \vec{\sigma}

    Try simply \bold{\sigma}

    You need the LaTeX package amsbsy (or amsmath). Put


    near the top of your document, and then use $\boldsymbol\sigma$.

    And if you want to make all your vectors boldface, I suggest something like


    in the preamble of your document and just use \vec everywhere. If you later decide that boldface is not distinctive enough and you want arrows after all, it will save you a lot of work.
