Solution Summary: The author determines that P (2) is true. For each positive integer n, let P (n) be the property 2n(n+1)!
This means that when the Radius of Convergence of the Power Series is a "finite positive real number" r>0, then every point x of the Power Series on (-r, r) will absolutely converge (x ∈ (-r, r)). Moreover, every point x on the Power Series (-∞, -r)U(r, +∞) will diverge (|x| >r). Please explain it.
Explain the conditions under which Radious of Convergence of Power Series is infinite. Explain what will happen?
