A new application of Chebyshev polynomials of second kind Un(x) to functions of two-dimensional operators is derived and discussed. It is related to the Hamilton-Cayley identity for operators or matrices which allows to reduce powers and smooth functions of them to superpositions of the first N-1 powers of the considered operator in N-dimensional ://?paperid=   Example For the numbers in example we have (i) z 1 = eiπ/2, (ii) z 2 = 2e−iπ/4, and (iii) z 3 =2e−iπ/6.

The use of Taylor series is an effective numerical method to solve ordinary differential equations but this fails when the sought function is not analytic or when it has singularities close to the domain.

These drawbacks can be partially removed by considering multi-point Taylor series, but up to now there are only few applications of the latter method in the literature and not for   Many of the properties related to convergence of complex functions can be extended from their counterparts of complex numbers.

For example, a necessary but not suﬃcient condition for the inﬁnite series of complex functions to converge is that lim k→∞ fk(z) = 0, for all zin the region of convergence.

From the discussion so far, it is evident that complex polynomials are analytic everywhere in C. Likewise, functions that are de ned in terms of power series, including the complex exponential and complex sines and cosines, are analytic everywhere in C.

Functions ~ydchong/teaching/   Let us now consider several classical Taylor series expansions. For the following examples we will assume that all of the functions involved can be expanded into power series. Example 1. The function f(x) = ex satis es f(n)(x) = ex for any integer n 1 and in particular f(n)(0) = 1 for all n and then the Maclaurin series of f(x) is f(x) = X1 n=0 ~aache/Files/   Analytic functions achieve a new level of smoothness—they can be diﬀerentiated forever.
