Homework Help: SHM ODE Problem

  1. Apr 4, 2012 #1
    1. The problem statement, all variables and given/known data

    I've got

    y'' - ω2y = sin(ωx) + sinh(ωx) where y(a) = A, y(b) = B

    2. Relevant equations

    3. The attempt at a solution

    Yc = C1 Sinh(ωx) + C2 Cosh(ωx)

    and I got my Yp to be -1/2*sin(ωx) + 1/2*sinh(ωx)

    I'm not sure about getting the Y general. Any pointers?

    The whole point of finding "Yc" and "Yp" is that the general solution to the entire equation is the sum of those.
