y^{''}+9y=cos(3t)

Lösung

y^{^{''}} + 9 y = cos (3 t)

y = c_{1} cos (3 t) + c_{2} sin (3 t) + \frac{t sin ( 3 t )}{6}

Schritte zur Lösung

y^{''} (t) + 9 y = cos (3 t)

Solve linear ODE:

y = c_{1} cos (3 t) + c_{2} sin (3 t) + \frac{t sin ( 3 t )}{6}

y = c_{1} cos (3 t) + c_{2} sin (3 t) + \frac{t sin ( 3 t )}{6}

\int x^{2} \cdot 1 + x d x

\frac{\partial}{\partial x} (- e^{8 y} cos (8 x) \cdot 8)
