Homework Statement
Find L[x(t)], where $$ x(t) = tu(t) + 3e^{-1}u(-t) $$
Also determine the region of convergence
Homework Equations
Laplace properties, Laplace table:L[te-at = 1/(s+a)2
L[u(t)] = 1/s
L[t] = 1/s2
The Attempt at a Solution
I don't really know what to do with this as my table doesn't give the product of these two.
Do you just combine them like this?:
tu(t) ---> (1/s)(1/s2)
3e-3u(-t) ---> wait...
I don't even know if my table says anything about a transform for u(-t), could it be -1/s?
I was going to do this and then add them to each other. Also need help with RoC
