    Laplace Transformation

    Hi, just like to check my answer with someone for the this question

    calculate y"+9y=H(t-1) y(0)=0 y'(0)=-2 using laplace method
    H is heaviside fuction

    my solution:

    y=cos(3t)-2sin(3t)/3 + H(t-1)/9(H(t-1) + cos (3t-3) )

    thanks

    You can substitute your solution into the DE to check if it works or not.
