Question

L{e^(3t) - U(t-2)*e^(3t)}
Laplace this sucker.

Answer 1

step function , eh

Answer 2

1/(s-3) is first term
now second term

u(t-2) e^3(t-2)e^6


e^-2s e^6/s-3

Answer 3

where does the e^6 come from?

Answer 4

because it is u(t-2)

I had to write e^3t as e^(3(t-2)+6) = e^3(t-2) e^6

Answer 5

OHH thank you.
