y^{''}+4y=5t^2e^t

y^{^{''}} + 4 y = 5 t^{2} e^{t}

y = c_{1} cos (2 t) + c_{2} sin (2 t) + e^{t} t^{2} - \frac{4 e ^{t} t}{5} - \frac{2}{25} e^{t}

Solution steps

y^{''} (t) + 4 y = 5 t^{2} e^{t}

Solve linear ODE:

y = c_{1} cos (2 t) + c_{2} sin (2 t) + e^{t} t^{2} - \frac{4 e ^{t} t}{5} - \frac{2}{25} e^{t}

y = c_{1} cos (2 t) + c_{2} sin (2 t) + e^{t} t^{2} - \frac{4 e ^{t} t}{5} - \frac{2}{25} e^{t}
