(II) Construct a Table indicating the position $x$ of the mass in Fig. 2 at times $t=0,\left\{T, \frac{1}{2} T, \frac{3}{4} T, T,$ and $\frac{5}{4} T,$ where $T$ is \right. the period of oscillation. On a graph of $x$ vs. $t,$ plot these six points. Now connect these points with a smooth curve. Based on these simple considerations, does your curve resemble that of a cosine or sine wave?
