Problem 5E

Intervals of Convergence

In Exercise , (a) find the series’ radius and interval of convergence. For what values of x does the series converge (b) absolutely, (c) conditionally?

Step-by-Step Solution:

Step 1 of 5</p>

Here, we have to find

The series’ radius and interval of convergence.The value of x for which the series converges absolutely.The value of x for which the series converges conditionally.

.

Step 2 of 5</p>Let us use the root test in order to find the radius of convergence.

Therefore, according to the ratio test, a series is said to be absolutely convergent if

…..(1)

Therefore, according to our question, we have .

Thus,

Thus, using (1), we have

…..(2)

.

Therefore, from (2) we get the radius of convergence as 10 and the centre as .

Step 3 of 5</p>

Now let us test the convergence of the series at the endpoints.

At , we have the series as

.

This is a Divergent Geometric series with  and  such that .

At , we have the series as

.

We know that the infinite sum of any non zero constant diverges.

Therefore, the series diverges.
