    How to Transform a Piecewise Function Using the Second Shift Theorem?

    questions asks to write the piecewise function as a unit step function and then to find the laplace transform t(e^t) 0≤t≤5 0 t≥3 I know it should be along the lines of t(e^t) - t(e^t)u(t-5) which then goes to t(e^t) - (t-5)(e^(t-5))u(t-5) I know there should be more to...
