A:

Uh, Wikipedia? Although Big O notation (and algorithm analysis in general) is a pretty broad and substantial topic, so I doubt you're going to find a "quick solution" to learning it.

hey Daniel if now online now can u response?

Go through it. Don't be daunted by the size, it is big because it is thorough, not because it is difficult. Also see the associated lectures http://www.catonmat.net/blog/mit-introduction-to-algorithms-part-one (this is the link I have bookmarked. The lectures are at MIT, but the blogs commentary is also very good)

Introduction to Algorithms

Also, there are some great lectures out there on youtube and itunesU

A:

"Concrete Mathematics: A Foundation for Computer Science (2nd Edition)" would be another book recommendation I'd toss out there. Big O isn't that difficult but it can take a while to get the hang of what it is trying to convey.
