y^{''}+8y^'+20y=0,y(0)=1,y^'(0)=7

Lösung

y^{^{''}} + 8 y^{^{'}} + 20 y = 0, y (0) = 1, y^{^{'}} (0) = 7

Lösung

y = e^{- 4 t} (cos (2 t) + \frac{11}{2} sin (2 t))

Schritte zur Lösung

y^{''} (t) + 8 y^{'} (t) + 20 y = 0

Solve linear ODE:

y = e^{- 4 t} (cos (2 t) + \frac{11}{2} sin (2 t))

y = e^{- 4 t} (cos (2 t) + \frac{11}{2} sin (2 t))
