Homework Help: Frobenius DE

  1. Apr 17, 2007 #1
    I'm really getting stuck at this and i'm trying to read on it but it's confusing.

    I need just a start-up for this equation which is to be solved with the method of frobenius.

    3xy" - 4y' - xy = 0

    Just need a start.

    Any help is appreciated.

    Thank you

    Start by substituting a power series in x for y. y=sum(a_k*x^k). Do the derivatives and equate coefficients of equal powers. Go!
