y^{''}=-4y-4y^'

Lösung

y^{^{''}} = - 4 y - 4 y^{^{'}}

y = c_{1} e^{- 2 t} + c_{2} t e^{- 2 t}

Schritte zur Lösung

y^{''} (t) = - 4 y - 4 y^{'} (t)

Solve linear ODE:

y = c_{1} e^{- 2 t} + c_{2} t e^{- 2 t}

y = c_{1} e^{- 2 t} + c_{2} t e^{- 2 t}

\frac{\partial}{\partial y} (tan (y))

t an g e n t lo g_{2} (x + x^{- 2})

t \to \infty lim (t^{2})

x \to 2 + lim (\frac{e ^{- x}}{2 - x})

\int 2 x (x^{2} + 4)^{7} d x
