4th order DE

  1. Mar 25, 2012 #1
    I'm working on this equation and I think I remember how to do it, but my notes from this class are so scattered and I can't seem to find the section in my textbook.

    the problem is:

    y(4)-4y" = 16e2x

    can someone help me out with just getting started? Doesn't it have something to do with letting w=y" and w"=y4?

    You need to get the homogeneous solution and the particular solution.
    To obtain the homogeneous solution use the characteristic equation.
