What is another word for power series expansion?
Pronunciation: [pˈa͡ʊə sˈi͡əɹiz ɛkspˈanʃən] (IPA) 
A power series expansion refers to the representation of a function in terms of a power series. Some synonyms for power series expansion include Taylor series expansion, Maclaurin series expansion, and Fourier series expansion. The Taylor series expansion is a representation of a function about a point, while the Maclaurin series expansion is a special case of the Taylor series expansion where the series is centered at x=0. On the other hand, a Fourier series expansion is a representation of a periodic function as a sum of sinusoidal functions. Each of these expansions has unique properties and applications in various fields of mathematics, engineering, and physics.
