Homework Help: Integral of e^t / t possible?

  1. Oct 9, 2006 #1
    The problem has ty'' - (1 + t)y' + y = (t^2)e^2t

    y1 = 1 + t

    Solve by reduction of order

    When I solve by variation of parameters I get:

    y = .5te^2t - .5e^2t + ce^t + d(1 + t)

    But solving with reduction of order gives very difficult integrals

    Well I should have seen this one

    (ue^u - e^u)/u^2 is a quotient rule.
