# Finding the Interval of Convergence In Exercise 15-38. find the Interval of convergence of the power series. (Be sure in include a check for convergence at the endpoints of the interval.) ∑ n = 0 ∞ ( − 1 ) n + 1 ( x − 1 ) n + 1 n + 1

To determine

To Calculate: The Interval of convergence for the power series n=0(1)n+1(x1)n+1n+1.

Explanation

Given:

The power series is n=0(1)n+1(x1)n+1n+1.

Formula Used:

By ratio test, the series is convergent if

limn|un+1un|<1

Calculation:

Consider the power series,

n=0(1)n+1(x1)n+1n+1

The nth term of the series is

un=(1)n+1(x1)n+1n+1

The (n+1)th term of the series is

un+1=(1)n+2(x1)n+2n+2
