n=0 (5 points each) Suppose the power series an(x - 1)" converges for 1 = 4 and diverges for x = -4. Answer each question below as yes, no, or can not be determined. (a) Does the power series converge for x = -1? (b) Does the power series converge for x = -2? (c) Does the power series converge for x = 5? (d) Does the power series converge for x = 7?
please i need the question 9 and 10 for the detailed proof and
explaination ! thanks !

NO Question # 3. (3 marks) Consider the power series, f(x) = Žan(x+1)". Suppose we know that f(-4), as a series, diverges, while f(2) converges. Determine the radius of convergence of the power series for f'(). Precisely name the results we learned in Week 3 that you use, and where you are using them.
Convergence of a Power Series The of a power series is the set of all values of x for which the series converges. Consider C -a)". Let R be the radius of convergence of this series. There are neo only three possibilities: 1. The series converges only when x = a, and so R = 0 and the interval of convergence is {a}. 2. The series converges for all x, and so R= oo and the interval of convergence а...
True of False (g) does the power series from ∞ to n=1 (x−2)^n /n(−3)^n has a radius of convergence of 3. (h) If the terms an approach zero as n increases, then the series an converges? (i) If an diverges and bn diverges, then (an + bn) diverges. (j) A power series always converges at at least one point. (l) The series from ∞ to n=1 2^ (−1)^n converges?

For the power series $1(-5)", find the values of a for which the series converges absolutely, and the x-values for which it converges conditionally. Then give the interval of convergence and the radius of convergence. The region between the graph of f(x) = ? V In x and the x-axis, for « > 1, is revolved axis. Calculate the volume of the solid that is created. Hint: Use the Disk Method, and since the integral will be improper and you...
