y^{''}-3y+2y=e^tsin(t)

y^{^{''}} - 3 y + 2 y = e^{t} sin (t)

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

Solution steps

y^{''} (t) - 3 y + 2 y = e^{t} sin (t)

Solve linear ODE:

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

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