around x = 0 using the method of Frobenius leads to finding the relation
- 3r + 2)ao +Σ{(n + r − 2)(n + r − 1)an + (n + r − 1)an- }}=0
n=1
We assume that this is true. (You are NOT asked to show why this is true.)
[a] Use this relation to find the indicial equation and the indicial roots.
[b] Use this relation to find the recurrence relation for an S.
[c] Use this relation to find the solution(s) of this differential equation.
Write your answer in sigma notation and simplify it as much as possible.
