Well, in this particular case, as soon as you know that it's one of those Greek letters, you can look it up and see that it's called "nu" and therefore written \nu in LaTeX.

If it's a symbol, try texdoc symbols.

In general, try http://detexify.kirelabs.org/classify.html

Edit: Sorry, I just followed my own advice and found out that this is more likely to be a \mathcal{V}.
