(1.4) For what value of (a, b) will the solutions to exhibit oscillatory behavior ? (A) (1,2) (B) (1,0) (C) (1,-1) (D) (2,1) (E) All of the above

(1.1) Let L [·] denotes the Laplace transform. (A) The Laplace transform is a linear operation. (B) If L[F(t)] = F(s), then L[t2F(t)]= F(S)(C) If L[f(t)] = F(s) , then L = SF(s) - f(0). (D) If L[f(t)] = F(s) and L[g(t)] = G(s), then L[f* g(t)] = F(s)G(s), where * denotes the convolution integral. (E) All of the above statements are TRUE.
