Consider the Maclaurin series for ex2, given by
V(x)=n=0∑∞n!x2n.
Respond to the following.
a. Determine the radius of convergence R of V(x).
b. For x=1, decide whether the series converges absolutely, converges conditionally, or diverges. Provide justification.
c. For x=2, determine whether the series converges or diverges and support your conclusion with appropriate reasoning.
