    what method do we use?

    what method do we use to solve a homogeneous 2nd order differential equation with non-constant co-efficients?

    thanks for any help

    It varies from one DE to another. Some will succumb only to the series solution method, while others, like Cauchy-Euler, are very straight-forward guess-and-check problems. Did you have a particular problem in mind?

    Yeah but It's an assessment, I havnt actually done any of those methods (having never solved these unless the co-efficients are constants) so thanks for the help anyway

    Ah. Thank you for not posting problems for which you're getting graded. I would check out Chris's DE tutorial for ideas on methods. He has quite a few there (one omission is the series solution method.)
