WebIt is well known that a power series S ( x) = ∑ n ≥ 0 a n ( x − x 0) n converges within a circle x − x 0 < R of radius R. However, its value is determined by behavior of coefficients a n at infinity. Since R − 1 = lim n → ∞ a n n, the radius of convergence depends on how fast the coefficients grow. However, if sum-function S ...

Web0. You cannot "invert" a power series (P.S.) by inverting term by term. If you want to find the inverse of a function of which a powerseries representation is established, you got to kind of start all over. For example, there is a P.S. for sinx. But reciprocating these polynomial terms does not get the P.S. for the cosecant function. Web1 The function is f ( x) = 1 / ( 1 − x) and it asks to find a power series expansion expanded around x = a, which would be the general expansion as well as around x = 0 and x = 2. … philip morris youtube https://makcorals.com
