I need to find the Laplace transform of t*e-t*u(t-tau)
2. Homework Equations and attempt at solution
I know the general form of the transform, but my problem is in the time shift of the step function. If both parts of the expression were (t-tau), then I could just pull out an e(s*tau), but I have no idea what I'm supposed to do when one part has it and the other does not.
Can anyone help get me started?
