(Solved):
1. In (a), (b), use the basic definition of Laplace transform to find \( L[f(t)] \) : (a) \( f(t)= ...
1. In (a), (b), use the basic definition of Laplace transform to find \( L[f(t)] \) : (a) \( f(t)=e^{t} \cos t \) (10\%) (h) (10\%) Note: you need to identify the bound of \( s \) such that \( L[f(t)] \) exists.
