Detexify

The easiest way to search for a math symbol is Detexify. This webservices allows you to draw the symbol. It looks like this:

Other

You might need \qed, \qedsymbol, \blacksquare for proofs. It is the Tombstone \(\blacksquare\)

I've recently needed \(\dots, \ddots, \vdots\) (\dots, \ddots, \vdots) for a visualization in a matrix. Note that you can write ... instead of \dots, but you'll lose the semantics.
