The Convergence Criterion and Application of Series Expressed by Function Terms
Abstract: This article is mainly on the research and discussion in the further understanding of function series. Series is one of the difficult point of series expressed by function terms. As to the discussion of series expressed by function terms, we can from the basic concept, the discriminant method, application of. Simple, the paper puts forward the definition of series expressed by function terms, the concept of a series of uniform convergence function and the concept of power series. And the convergence of series expressed by function terms by learning, which further discusses the function item some simple applications of the series. This paper also focuses on the most basic function of the series - power series, its basic knowledge, made a more detailed induction and summary to this. Finally use it to solve series expressed by function terms we encountered in mathematics learning some of the problems, and by listing a lot of examples to illustrate the application of power series problem, also have more important application in reality.
Key words: Function series; Convergence criterion. Progression to application
