A simple harmonic oscillator of angular frequency $\displaystyle 2 \mathrm{rad} \mathrm{s}^{-1}$ is acted upon by an external force $\displaystyle \mathrm{F}=\sin t \mathrm{~N}$. If the oscillator is at rest in its equilibrium position at $\displaystyle t=0$, its position at later times is proportional to :
Official answer
(4)
$\displaystyle \sin t-\frac{1}{2} \sin 2 t$
