What in the world does this giant "less than" symbol mean? my e&m professor uses it on the chalkboard all the time... I want my stupidity to remain a secret as long as possible so I'm asking here, nicely. Call me a fool but you can't tell me anything about myself that I don't already know.

My professor uses it exclusively to denote a relationship between two functions.

Do you mean f(x) << g(x)?

If so, then this means that there exists some constant c such that for all x > c, |f(x)| < c|g(x)|.

It basically says that g(x) will "eventually" grow faster than f(x) in magnitude. See also: Big O notation.
