Q1:

If F(s) is the Laplace transform of f(t) then Laplace transform of

A

B sFU(s)

C s2F(s)

D

ANS:B - sFU(s)

£f(t) = £-1F(s) = f(t) £[a f1(t) + bf2(t)] = aF1(s) + bF2(s) where £[f(t - T)] = e-sT F(s) £[e-at f(t)] = F(s + a) Initial value theorem Final value theroem Convolution Integral where t is dummy variable for t.
