y^{''}+4y=0,y(pi/6)=4,y^'(pi/6)=-8

Lösung

y^{^{''}} + 4 y = 0, y (\frac{π}{6}) = 4, y^{^{'}} (\frac{π}{6}) = - 8

Lösung

y = (8 - 3 \cdot 2 (3 - 1)) cos (2 t) + 2 (3 - 1) sin (2 t)

Schritte zur Lösung

y^{''} (t) + 4 y = 0

Solve linear ODE:

y = (8 - 3 \cdot 2 (3 - 1)) cos (2 t) + 2 (3 - 1) sin (2 t)

y = (8 - 3 \cdot 2 (3 - 1)) cos (2 t) + 2 (3 - 1) sin (2 t)
