After setting out in the sums and collecting the terms in [tex]x^j[/tex] I'm left with a series of expressions in
[tex]a_2, a_3[/tex] etc as I believe I'm supposed to. However my first expression reads
[tex]2a_{2}+2a_{1}+a_-_{1}=0[/tex]
Now I'm told that
[tex]y(o) = 1[/tex] and
[tex]y'(o) = 0[/tex]
I think this means that
[tex]a_0 = 1[/tex]
and
[tex]a_1 = 0[/tex]
does this mean that
[tex]a_-_1 = x[/tex]?
(My other expressions are
[tex]6a_3+6a_2+a_0=0[/tex]
and
[tex]24a_4+12a_3+a_1=0[/tex])
i'm always left with an
[tex]a_-_1[/tex]
when finding the other
[tex]a_{j}[/tex]'s
