Mathematics QUESTION #1325

Question 1291

For the ODE $y''-2y'+2y=0$, the general solution using roots $r=1\pm i$ is:

$y=e^x(C_1+C_2 x)$
$y=C_1e^x\cos x+C_2e^x\sin x$✔️
$y=C_1\cos x+C_2\sin x$
$y=e^{-x}(C_1\cos x+C_2\sin x)$

Correct Answer Logic:

For complex roots $r=\alpha\pm\beta i$, the real general solution is $y=e^{\alpha x}(C_1\cos\beta x+C_2\sin\beta x)$. Here $\alpha=1$, $\beta=1$, so $y=e^x(C_1\cos x+C_2\sin x)$.
