Laplace Transform f(t) = e^t *sin(t)sin(5t)

  1. Mar 30, 2008 #1
    Hey everyone

    Does anyone know how to do the following Laplace Transformation

    f(t) = e^t *sin(t)sin(5t)

    i can do it with one sin function but don't know how to do it with 2.

    any help would be appreciated.

    Use the addition formula for sines:

    sin(t)sin(5t) = (cos(4t) - cos(6t))/2
