k=1 Question 4. Suppose that the power series ax (x – 2)* converges at x = 5 and diverges at x = -7. Write four real numbers at which the series converges and two real numbers at which the series diverges. What can you say about the radius of convergence? Explain your answers clearly.
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...
