solve by frobenius method 2xy"+(1+x)y'-2y=0​

Answer 1

Answer:

Use the Frobenius method to solve x2y″+xy′+y=0 about x=0. x=0 is a singular regular point. My problem is the roots of the indicial equation are −i ...

So you have the roots ±i, normally you order them by largest real part, but obviously the real parts are the same, so lets set α1=i,α2=−i. Then the
