(such as Mathieu’s equation) and then, as an extension of some of the ideas already developed, the method of strained coordinates is presented One of the most general and most powerful techniques in the armoury of singular perturbation theory is the method of multiple scales This is introduced, explained and developed in Chapter 4, and then applied to a wide variety of problems These include linear and. .. is big-oh of g as or simply ‘ f is order g as As examples, we offer but also 12 1 Mathematical preliminaries finally but (Little-oh and big-oh–o and O—are usually called the Landau symbols.)
