Radius of convergence of power series calculator.
Nov 16, 2022 · A power series about a, or just power series, is any series that can be written in the form, ∞ ∑ n=0cn(x −a)n ∑ n = 0 ∞ c n ( x − a) n. where a a and cn c n are numbers. The cn c n ’s are often called the coefficients of the series. The first thing to notice about a power series is that it is a function of x x.
When they are the same, you only can say that it is greater equal than the convergence radius.
