Homework Statement
using the fact that [tex]\frac{sint}{t}[/tex] = [tex]\sum^{}_{n=0}[/tex][tex]\frac{ (-1)[tex]^{n}[/tex] t[tex]^{2n}[/tex]}{(2n+1)!}[/tex]
i wanted to write:
using that sint/t = ∑ (-1)ⁿ·t²ⁿ/(2n+1)!
find a power series solution of the equation tx'' +sint x = 0

sorry i pushed the wrong button,
The Attempt at a Solution
I'm a beginner at LaTeX, a disaster at LaTeX
i get something like ∑n(n-1)a_nt^(n-2) +sint∑a_n = 0
