    Laplace transform

    What is the laplace transform of sinh(3t - 4)?

    I have Laplace of sinh(3t - 4) = integral from 0 to infinity of exp(-pt).f(t)dt
    let u = 3t -4
    dt = 1/3 du

    1/3 integral of from 0 to infinity of exp(-pt)sinhu du
    and now i'm stuck

    Try using:

    \sinh(x)=\dfrac{e^x-e^{-x}}{2}
