Mathematics · Differential Equations
The general solution of the differential equation y'' + y = 6 sin x is:
- 1y(x) = C1 cos x + C2 sin x - 3x cos x✓
- 2y(x) = C1 cos x + C2 sin x - 3 sin x
- 3y(x) = C1ex + C2e-x - 3x cos x
- 4y(x) = C1ex + C2e-x + 3x cos x
Correct answer
y(x) = C1 cos x + C2 sin x - 3x cos x
