What happens when radius of convergence is 1?

In our example, the center of the power series is 0, the interval of convergence is the interval from -1 to 1 (note the vagueness about the end points of the interval), its length is 2, so the radius of convergence equals 1.

Why is it called radius of convergence?

It's called a radius of convergence because mathematicians like to plug in complex numbers, like X = U + i V, where i * i = -1. They can show that the series converges inside a circle U2 + V2 = R2, and diverges outside the circle

How do you test endpoints of convergence?

The endpoints of the interval of convergence must be checked separately, as the Root and Ratio Tests are inconclusive there (when x=±1L, the limit is 1). To check convergence at the endpoints, we put each endpoint in for x, giving us a normal series (no longer a power series) to consider.

What is Radius Of Convergence?

The power series converges only for certain values. The Radius of convergence is called the converges of some interval on power series distance from the centre of convergence to the other end of the interval.
The ratio test is mostly used to determined the power series of the Radius of convergence and the test instructs to find the limit. It predicts from the point of limit is less than 1.
In the positive power series uniformly on compact set and converges absolutely of inside radius is equal to convergence of radius. In either non- negative real number or infinity.
