Homework Help: Laplace Transform of Delta Function

  1. Nov 18, 2012 #1
    1. The problem statement, all variables and given/known data
    Evaluate the Laplace transform: L{δ(t-∏)tan(t)}

    2. Relevant equations

    3. The attempt at a solution
    L{δ(t-∏)tan(t)} = ∫ δ(t-∏)tan(t) dt evaluated from 0 to ∞
    = 0

    Could someone check my work on this one? I'm suspicious that my transform is just zero. Thanks!!

    You omitted the e^(-st) factor in the definition of the Laplace transform, but sure, 0 is correct.
