y^{''}+g^2y=cos(2t),y(0)=1,y^'(0)=0

Lösung

y^{^{''}} + g^{2} y = cos (2 t), y (0) = 1, y^{^{'}} (0) = 0

y = \frac{cos ( 2 t )}{g ^{2} - 4} + cos (g t) (- \frac{1}{g ^{2} - 4} + 1)

Schritte zur Lösung

y^{''} (t) + g^{2} y = cos (2 t)

Solve linear ODE:

y = \frac{cos ( 2 t )}{g ^{2} - 4} + cos (g t) (- \frac{1}{g ^{2} - 4} + 1)

y = \frac{cos ( 2 t )}{g ^{2} - 4} + cos (g t) (- \frac{1}{g ^{2} - 4} + 1)

y^{^{''}} - 4 y^{^{'}} - 5 y = 3 e^{- 4 t}

y^{^{''}} + 4 y = 6 cos (2 t), y (0) = 2, y^{^{'}} (0) = 1

y^{^{''}} - 9 y = - 27 t + 18 t^{2}

y^{^{'''}} - 2 y^{^{''}} + 26 y^{^{'}} = 174 e^{3 x}

y^{^{''}} + y^{^{'}} - y = t^{3}, y (0) = 1, y^{^{'}} (0) = 0
