y^{''}+4y=8sin(2t)+5e^t

y^{^{''}} + 4 y = 8 sin (2 t) + 5 e^{t}

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

Solution steps

y^{''} (t) + 4 y = 8 sin (2 t) + 5 e^{t}

Solve linear ODE:

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

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