Hi!(adsbygoogle = window.adsbygoogle || []).push({});

I've got a problem with understanding notation in this lecture:

http://www.youtube.com/watch?v=FZDy_Dccv4s&feature=BFa&list=PLF4D952FA51A49E66

For example, at 00:44:13, what does all lowercase deltas stand for? He writes:

δA=∫(∂L/∂q)δq + (∂L/(∂q dot))δ(q dot)

Why lowecase delta? What kind of notation is that?

There is kind of a brief explanation at 00:23:00 but I don't really get it. If someone can show that a bit more clearly that would be helpful.
