y^{''}-14y^'+49y=t^{-2}e^{7t}

Lösung

y^{^{''}} - 14 y^{^{'}} + 49 y = t^{- 2} e^{7 t}

y = c_{1} e^{7 t} + c_{2} t e^{7 t} - e^{7 t} ln (t) - e^{7 t}

Schritte zur Lösung

y^{''} (t) - 14 y^{'} (t) + 49 y = t^{- 2} e^{7 t}

Solve linear ODE:

y = c_{1} e^{7 t} + c_{2} t e^{7 t} - e^{7 t} ln (t) - e^{7 t}

y = c_{1} e^{7 t} + c_{2} t e^{7 t} - e^{7 t} ln (t) - e^{7 t}
