Determine a differential equation that has x = 0 as a regular
singular point and that the roots of the index equation are i and

Given that x =0 is a regular singular point of the given
differential equation, show that the indicial roots of the

Determine if x = 0 is an ordinary point, regular singular point, or
irregualr singlar point for the following. Make sure to give
reasons.
a) y" + (2/x)y' + (5e^x)y = 0
b) x(1-x)y" + 4y' + y =0
