y^{''}+4y=t-2sin(2t)

y^{^{''}} + 4 y = t - 2 sin (2 t)

y = c_{1} cos (2 t) + c_{2} sin (2 t) + \frac{t}{4} + \frac{t cos ( 2 t )}{2}

Solution steps

y^{''} (t) + 4 y = t - 2 sin (2 t)

Solve linear ODE:

y = c_{1} cos (2 t) + c_{2} sin (2 t) + \frac{t}{4} + \frac{t cos ( 2 t )}{2}

y = c_{1} cos (2 t) + c_{2} sin (2 t) + \frac{t}{4} + \frac{t cos ( 2 t )}{2}
