In the same way as we did with Taylor series, we typically use the Ratio Test to find the values of \(x\) for which the power series converges absolutely, and then check the endpoints ...The radius of convergence will be R = (c – b) / 2. Two extremes are possible: The radius of convergence can be zero, which will result in an interval of convergence with a single point, a (the interval of convergence is never empty). Or, for power series which is convergent for all x-values, the radius of convergence is +∞.
