6y^{''}+6y^'+73y=8cos(4x)

Lösung

6 y^{^{''}} + 6 y^{^{'}} + 73 y = 8 cos (4 x)

y = e^{- \frac{x}{2}} (c_{1} cos (\frac{143 x}{2 3}) + c_{2} sin (\frac{143 x}{2 3})) + \frac{192}{1105} sin (4 x) - \frac{184}{1105} cos (4 x)

Schritte zur Lösung

6 y^{''} (x) + 6 y^{'} (x) + 73 y = 8 cos (4 x)

Solve linear ODE:

y = e^{- \frac{x}{2}} (c_{1} cos (\frac{143 x}{2 3}) + c_{2} sin (\frac{143 x}{2 3})) + \frac{192}{1105} sin (4 x) - \frac{184}{1105} cos (4 x)

y = e^{- \frac{x}{2}} (c_{1} cos (\frac{143 x}{2 3}) + c_{2} sin (\frac{143 x}{2 3})) + \frac{192}{1105} sin (4 x) - \frac{184}{1105} cos (4 x)

\frac{d ^{2} y}{d x ^{2}} - \frac{d y}{d x} - 6 y = - e^{x} + 12 x

y^{^{''}} + 2 y^{^{'}} - 3 y = 2 cos (x) - 4 sin (x)

\frac{1}{2} y^{^{''}} + 2 y = 4 tan (2 t) - \frac{1}{3} e^{t}

38 y^{^{''}} - 7 y = \frac{5}{2}

3 y^{^{''}} + 12 y = - 4 sin (3 t)
