$r=\frac{sin \theta}{\theta}$ Since $r \to 0$ as $\theta \to \infty$, the curve resembles an oscillating curve becoming flatter and flatter as $r$ increases.
$r=\frac{sin \theta}{\theta}$ Since $r \to 0$ as $\theta \to \infty$, the curve resembles an oscillating curve becoming flatter and flatter as $r$ increases. See the attached graph. The graph is symmetrical about the x-axis, so the negative y-axis values should show a mirror image of the positive y-axis values.
