    [SOLVED] nth Order Linear Equations

    Hey all, I could use some help with this problem:

    Determine the intervals in which solutions are sure to exist:
    (x-1)y\prime\prime\prime\prime + (x+1)y\prime\prime + (\tan x)y = 0

    Not really sure how to approach this. What am I supposed to be doing?


    Minutes after posting this, I figured it out, haaa. Divide all terms by (x-1) and that makes life easier.
