However, no matter how high you increase the index of summation, the blue graph never follows the original red graph outside of the interval of convergence -1<=x<=1 Adjust the upper limit of summation (i) to get closer and closer to infinity and see how it affects the Taylor Expansion of 1/(1-x).In that case, the power series either converges for all real numbers x or converges for all x in a finite interval. For example, the geometric series [latex]\displaystyle\sum _{n=0}^{\infty }{x}^{n}[/latex] converges for all x in the interval [latex]\left(-1,1\right)[/latex], but diverges for all x outside that interval. We now summarize these ... Explain the radius of convergence of a power series. We’ve developed enough machinery to look at the convergence of power series. The fundamental result is the following theorem due to Abel. Theorem 8.3.1 8.3. 1. Suppose ∑n=0∞ ancn ∑ n = 0 ∞ a n c n converges for some nonzero real number c c. Then ∑n=0∞ anxn ∑ n = 0 ∞ a n x n ...Power Series: Radius and Interval of Convergence. A power series ( centered at the origin) is an expression of the form: ∑ n = 0 ∞ c n x n = c 0 + c 1 x + c 2 x 2 + c 3 x 3 + …. where x is a variable and each c n is a cofficient, which is a constant (perhaps different constants, depending upon n ). For example, For each of the following functions, find the Maclaurin series and its interval of convergence.
