In using power series for computation the main problems are: 1) To predict a priori the number N of terms needed to do the computation with a specified accuracy; and 2) To find the coefficients aO, ¿.¿ ,a ¿ N These are the problems addressed in the book. Typical computations envisioned are: -6 calculate with error ~ 10 the integrals If\/2 J (If\/2-x)tan x dx o or the solution to the differential equation 2 y\"+(sin x)Y'+x y = 0, y(O) = 0, y'(O) 1, on the interval 0 ~ x ~ 1. This computational point of view may seem narrow, but, in fact, such computations require the understa- ing and use of many of the important theorems of ele­ mentary analytic function theory: Cauchy's Integral Theorem, Cauchy's Inequalities, Unique Continuation, Analytic Continuation and the Monodromy Theorem, etc. The computations provide an effective motivation for learning the theorems and a sound basis for understa- ing them. To other scientists the rationale for the vi computational point of view might be the need for ef- cient accurate calculation; to mathematicians it is the motivation for learning theorems and the practice with inequalities, ~'s, o's, and N's.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9780387965161\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9780387965161","offer_id":39414840852573,"sku":"9780387965161","price":106.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/a87125d2-3da7-47fe-b204-6cdf8e59f2e1.jpg?v=1772169029","url":"https:\/\/shop.autorenwelt.de\/en\/products\/power-series-from-a-computational-point-of-view-von-kennan-t-smith","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
