y^{''}-2y^'-3y=2cos(3x)

Lösung

y^{^{''}} - 2 y^{^{'}} - 3 y = 2 cos (3 x)

Lösung

y = c_{1} e^{3 x} + c_{2} e^{- x} - \frac{1}{15} sin (3 x) - \frac{2}{15} cos (3 x)

Schritte zur Lösung

y^{''} (x) - 2 y^{'} (x) - 3 y = 2 cos (3 x)

Solve linear ODE:

y = c_{1} e^{3 x} + c_{2} e^{- x} - \frac{1}{15} sin (3 x) - \frac{2}{15} cos (3 x)

y = c_{1} e^{3 x} + c_{2} e^{- x} - \frac{1}{15} sin (3 x) - \frac{2}{15} cos (3 x)
