y^{''}+2y^'+y=8e^{-t}

Lösung

y^{^{''}} + 2 y^{^{'}} + y = 8 e^{- t}

y = c_{1} e^{- t} + c_{2} t e^{- t} + 4 t^{2} e^{- t}

Schritte zur Lösung

y^{''} (t) + 2 y^{'} (t) + y = 8 e^{- t}

Solve linear ODE:

y = c_{1} e^{- t} + c_{2} t e^{- t} + 4 t^{2} e^{- t}

y = c_{1} e^{- t} + c_{2} t e^{- t} + 4 t^{2} e^{- t}

\frac{d y}{d x} = - \frac{2 x y + y ^{2} + 1}{x ^{2} + 2 x y}

k = 1 \sum \infty \frac{2 ^{k}}{k !}
