Homework Help: Newton's second law, how to write it?

  1. Oct 15, 2014 #1
    Very stupid question, but I am writing out my problem and need this formula;
    in typed symbols, so I can copy and paste it into my document. Like √

    Hope that makes sense...

    \Sigma F=ma

    Better - \sum F = ma

    This renders as $$\sum F = ma$$
    If you use Sigma, the uppercase Greek letter, it renders in the same size as whatever follow it, like so:
    $$\Sigma F = ma$$
