Local comparison of functions. Numerical sequences and series

Part of the UNITEXT book series (UNITEXT, volume 84)


In the first part of this chapter we learn how to compare the behaviour of two functions in the neighbourhood of a point. To this aim, we introduce suitable symbols — known as Landau symbols — that make the description of the possible types of behaviour easier. Of particular importance is the comparison between functions tending to 0 or ∞.
