www.math.hkust.edu.hk5. Taylor and Laurent series Complex sequences and series An infinite sequence of complex numbers, denoted by {zn}, can be considered as a function defined on a set of positive integers into the unextended complex plane. For example, we take zn= n+ 1 2n so that the complex sequence is {zn} = ˆ1 + i 2, 2 + i 22, 3 + i 23 ...
Series - math.ucdavis.edu
www.math.ucdavis.edusequences, we may start a series at other values of nthan n= 1 without changing its convergence properties. It is sometimes convenient to omit the limits on a series when they aren’t important, and write it as P a n. Example 4.2. If jaj<1, then the geometric series with ratio aconverges and its sum is X1 n=0 an= 1 1 a:

ncert.nic.inFor example, 1 + 3 + 5 + 7 is a finite series with four terms. When we use the phrase “sum of a series,” we will mean the number that results from adding the terms, the sum of the series is 16. We now consider some examples. Example 1 Write the first three terms in each of the following sequences defined by the following: (i) an = 2n + 5 ...
