It is an explanation of the Cauchy-Hadamard theorem on power series. Cauchy- Hadamard Theorem :- ∞ For every power series ∑ anzn there exist a number R, 0 ≤ R < ∞ n=0 called the radius of convergence with the following properties: (i) The series converges absolutely for every |z| < R (ii) If 0 ≤ ρ < R, the series converges uniformly for |z| ≤ ρ (iii) If |z| > R, the terms of the series are unbounded and the series is consequently divergent.
