I think the question is to find the radius of convergence, not to "calculate" the series (I doubt that the sum of the series has a closed-form expression). If |x| < 1 | x | < 1 this goes to 0 0 as n → ∞ n → ∞, and thus is less than 1 1 for sufficiently large n n, thus the series converges.

The limitations of Taylor's series include poor convergence for some functions, accuracy dependent on number of terms and proximity to expansion point, limited radius of convergence, inaccurate representation for non-linear and complex functions, and potential loss of efficiency with increasing terms.A power series is basically an infinite series that is comparable to a polynomial with many terms. The power series will usually converge to a value “x” within a given period, such that the absolute value of x is less than some positive number “r,” which is known as the radius of convergence .In this section we’ll state the main theorem we need about the convergence of power series.

Alternatively, you can easily show that the radius of convergence ρ−1 =lim supn→∞ |an|−−−√n ρ − 1 = lim sup n → ∞ | a n | n satisfies ρ−1 ≤ 1 ρ − 1 ≤ 1, since C−−√n − →−−n→∞ 1 C n → n → ∞ 1 for all C > 0 C > 0. If you look at the proof of this formula for the radius of convergence (usually ...terms in the power series approaches a limit: a n+1x n+1 a nxn = a n+1 a n x ! jxj c; as n!1 The ratio test from Lectures Part 4 says the series converges if jxj<c:and diverges if jxj>c: Why? (Extra Credit). So c= R, the radius of convergence. This comes from the de–nition of radius of convergence as a least upper bound. IfYour interval of convergence extends from c-r < x < c+r. Since r=0, your power series only converges at the single point x=c (x=0). If we had gotten any other nonzero value for r, we would have defined an open interval where the power series converges absolutely. The next step would be to test the two endpoints of the interval to …A power series in a variable z is an infinite sum of the form sum_(i=0)^inftya_iz^i, where a_i are integers, real numbers, complex numbers, or any other quantities of a given type. Pólya conjectured that if a function has a power series with integer coefficients and radius of convergence 1, then either the function is rational or …Succinctly, we get the following for power series centered at the origin: Let ∞ ∑ n = 0cnxn have radius of convergence R . As long as x is strictly inside the interval of convergence of the series, i.e. − R < x < R, ∫( ∞ ∑ n = 0cnxn)dx = ( ∞ ∑ n = 0cnxn + 1 n + 1) + C and the new series have the same R as the original series.

Convergence of a Power Series. Since the terms in a power series involve a variable x, the series may converge for certain values of x and diverge for other values of x. For a power series centered at x = a, x = a, the value of the series at x = a x = a is given by c 0. c 0. Therefore, a power series always converges at its center.
