For the following ODE
4. xy'' +y' -xy = 0; x0 = 0
a) What are the points of singularity for the problem?
b) Does this ODE hold a general power series solution at the
specific x0? Justify your answer,
i) if your answer is yes, the proceed as follows: Compute the
radius of analyticity and report the corresponding interval, and
Identify the recursion formula for the power series coefficient
around x0, and write the corresponding solution with at least...
