Laplace Transform of Delta Function

[digipony]

Homework Statement

Evaluate the Laplace transform: L{δ(t-∏)tan(t)}

Homework Equations

The Attempt at a Solution

L{δ(t-∏)tan(t)} = ∫ δ(t-∏)tan(t) dt evaluated from 0 to ∞
=tan(∏)e^-∏*s
= 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.
