Concept to differential equations

  1. Aug 28, 2013 #1
    Question: Explain why you cannot solve the ordinary equation?

    x^2y'' + xy' + (x^2-1)y = 0

    My attempt: I don't need to solve it, but just simply state why I can't with just differential equations
    So my answer is, This differential equation does have a solution, it's just not expressable in closed form.

    I don't know if I should add on to this or does this get my point across

    Don't series solutions qualify as "just differential equations"? Is your question given in the context of studying singular points?

    Well this is just to refresh on my differential skills, this class is applied analysis and the professor wanted us to explain this
