Find the solution of y'' + 6y' + 9 = 0, y(0) = 2, y'(0) = 1.

Find the solution of $y'' + 6y' + 9 = 0$, $y(0) = 2$, $y'(0) = 1$. [5]

  • ODE: $y'' + 6y' + 9 = 0$ - Initial conditions: $y(0) = 2$, $y'(0) = 1$ Note: As written, the equation contains a constant term "$+9$" rather than "$+9y$". Read literally, $y'' + 6y' = -9$ is a non-homogeneous equation. However, the standard textbook problem (and the one that produces a clean se...
