Homework Statement
Solve ##(1-x)y''+y=0## at the point ##x_0=0##. Use this solution to find a solution to ##xy''+y=0## around the point ##x_0=1##.
Homework Equations
The Attempt at a Solution
##(1-x)y''+y=0##
##(x-1)y''=y##
##\displaystyle\sum_{k=2}^\infty a_k k (k-1)\left(x^{k+3}-x^{k+2}\right)=\displaystyle\sum_{k=0}^\infty a_k x^k##
I tried to find a recurrence relation for ##a_k##, but I keep getting 0 for all k. I realize that y = 0 is a solution, but I don't know how that would help me in the second part.
