y^{''}+5y^'+4y=sin(3x)

Lösung

y^{^{''}} + 5 y^{^{'}} + 4 y = sin (3 x)

y = c_{1} e^{- x} + c_{2} e^{- 4 x} - \frac{1}{50} sin (3 x) - \frac{3}{50} cos (3 x)

Schritte zur Lösung

y^{''} (x) + 5 y^{'} (x) + 4 y = sin (3 x)

Solve linear ODE:

y = c_{1} e^{- x} + c_{2} e^{- 4 x} - \frac{1}{50} sin (3 x) - \frac{3}{50} cos (3 x)

y = c_{1} e^{- x} + c_{2} e^{- 4 x} - \frac{1}{50} sin (3 x) - \frac{3}{50} cos (3 x)
