Using the given equations, $x=t+\sin(t)$ and $y=\cos(t)$ create a table of values in terms of $x$ and $y$, using values of $t$ within the given interval ($−\pi\leq t\leq \pi$). Then, plot the calculated points from the lowest $t$ value to the highest $t$ value. This will give the direction of the curve.
