y^{''}-8y^{''}-9y=0

Lösung

y^{^{''}} - 8 y^{^{''}} - 9 y = 0

Lösung

y = c_{1} cos (\frac{3 t}{7}) + c_{2} sin (\frac{3 t}{7})

Schritte zur Lösung

y^{''} (t) - 8 y^{''} (t) - 9 y = 0

Solve linear ODE:

y = c_{1} cos (\frac{3 t}{7}) + c_{2} sin (\frac{3 t}{7})

y = c_{1} cos (\frac{3 t}{7}) + c_{2} sin (\frac{3 t}{7})
