Solve the Ordinary Differential Equation y + 2y + 5y = e-t sin(t) when y(0) = 0 and y (0) = 1.(Without solving for the constants we get in the partial fractions). |
A. | (e^t [Acost+A1sint+Bcos(2t)+ frac{(B1)}{2} sin(2t)] ) |
B. | (e^{-t} [Acost+A1sint+Bcos(2t)+B1sin(2t)] ) |
C. | (e^{-t} [Acost+A1sint+Bcos(2t)+ frac{(B1)}{2} sin(2t)] ) |
D. | (e^t [Acost+A1sint+Bcos(2t)+(B1)sin(2t)] ) |
Answer» D. (e^t [Acost+A1sint+Bcos(2t)+(B1)sin(2t)] ) | |
