Hello all, I've come across big and little o notation a few times now in my mathematics studies, but only ever on a single homework assignment ("use taylor series to find the limit," that kind of thing) or a brief mention in a textbook. However, one of my instructors suggested in office hours recently that it was an extremely important tool. I'm looking for resources, especially practice problems, on using and manipulating asymptotic notation in a general context. I am also currently taking a first course in analysis and would be interested in any materials applying asymptotic notation to that subject. If there was a calculus-textbook style book over nothing but this subject that would be awesome, but I honestly don't even know what search terms to use to look for this. Thanks for any and all advice you good people might have.
