A Quick Note on Calculating the Radius of Convergence

WebThe radius of convergence of a power series f centered on a point a is equal to the distance from a to the nearest point where f cannot be defined in a way that makes it holomorphic. The set of all points whose distance to a is strictly less than the radius of convergence is called the disk of convergence. WebShare a link to this widget: More. Embed this widget » Webnj : Again, the result is that f(z) converges absolutely on the open disk of radius R about c, and this convergence is uniform on compacta, but f(z) diverges if jz cj> R. We now establish this. We may take c= 0. Suppose rst that Ris nite. Let Kbe a nonempty compact subset of the open disk of radius R. a te jovanotti lyrics español
