Power Series: Radius and Interval of Convergence

A power series (centered at the origin) is an expression of the form: ∞∑n=0anxn=a0+a1x+a2x2+a3x3+…

where x is a variable and each ai is a fixed number. For example, ∞∑n=0xnn!, or ∞∑n=0xnn+1.


Definitions:
The set of x where the series converges is called the interval of convergence, and is an interval from −R to R, where R≥0 is a called the radius of convergence.


The interval of convergence may include one, both, or no endpoints, for which we have to check separately.

Special cases:

  • If R=0, then the series converges at the single point x=0;
  • If R=∞, then the series converges on the entire real line.
