You may be interested in studying uniform convergence of sequences and series of functions for …Sometimes we’ll be asked for the radius and interval of convergence of a Maclaurin series. In order to find these things, we’ll first have to find a power series representation for the Maclaurin series, which we can do by hand, or using a table of common Maclaurin series.The radius of convergence is the distance between the centre of convergence and the other end of the interval when the power series converges on some interval. The ratio test can be used to calculate the radius of convergence of a power series. The best test to determine convergence is the ratio test, which teaches to locate the limit. If the ... Ratio Test. Suppose we have the series ∑an ∑ a n. Define, if L < 1 L < 1 the series is absolutely convergent (and hence convergent). if L > 1 L > 1 the series is divergent. if L = 1 L = 1 the series may be divergent, conditionally convergent, or absolutely convergent. A proof of this test is at the end of the section.

The radius of convergence is half of the interval of convergence. In the video, the interval is -5 to 5, which is an interval of 10, so the radius of convergence is 5. (This is unaffected by whether the endpoints of the interval are included or not)

The cn c n ’s are often called the coefficients of the series. The first thing to notice about a power series is that it is a function of x x. Your 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 …
