In general, given a power series function, it is difficult (if not impossible) to express the function in terms of elementary functions.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 +∞.The radius of convergence “R” is any number such that the power series will converge for |x – a| < R and diverge for |x – a| > R. The power series may not converge for |x – a| = R. From this, we can define the interval of convergence as follows. The interval of all x values, including the endpoints (if required) for which the power ...
