Homework Statement
Find the recurrence relation for the following differential equation. You
do not need to solve the rest of the way.
y" − 2xy = 0
The Attempt at a Solution
I'm not exactly sure how to do this problem but from the example of the book I tried this:
y"-2xy= [tex]\sum[/tex] cnn(n-1)xn-2- 2x[tex]\sum[/tex] cnxn+1 and replaced k=n-2 and k=n+1 simultaneously and kinda ended up with
(k+1)(k+2)ck+2+2ck-1= 0 k=1,2,3...
Is that correct?
