y^{''}+9y=-30sin(3t)

Lösung

y^{^{''}} + 9 y = - 30 sin (3 t)

y = c_{1} cos (3 t) + c_{2} sin (3 t) + 5 t cos (3 t)

Schritte zur Lösung

y^{''} (t) + 9 y = - 30 sin (3 t)

Solve linear ODE:

y = c_{1} cos (3 t) + c_{2} sin (3 t) + 5 t cos (3 t)

y = c_{1} cos (3 t) + c_{2} sin (3 t) + 5 t cos (3 t)

\frac{d}{d x} (ln (sec (x) - tan (x)))

\frac{d}{d x} (\frac{2 - x}{x})

\int_{- π}^{π} cos (n x) d x

y^{^{'}} = cos (x)
