Homework Help: Need some help with Diff. eq.

  1. May 8, 2006 #1
    Hi community :P

    Need some help with a differential Equation:


    actually i'm looking for an asymptotic solution, when x -> infinity.

    I made some research about that Eq. and here what i have found:

    1 guy found an asymptotic sol. for a more general eq.:

    Hershenov, J. Solutions of the differential equation y''' +axy'+by = 0. Stud. Appl. Math. 55 (1976), 301-314.

    other guy found a solution of a more general eq:

    Pfeiffer, G. W. Asymptotic solutions of y"'+q(x)y'+r(x)y=0. J. Differential Equations 11 (1972), 145-155.

    but unfortunaly i cant find any of those articles.

    and the last thing which i know:

    the eq. y'''-4xy'-2y=0 is a generaliaed Airy's eq. whose solutions are well studied.....but its not a thing im looking for....

    any advice is very appreciated.
    and if some one could find one of those articles i'll appreciate that VERY MUCH!!!!

    Thx for your concideration.

    PS: Sorry my bad english.
