$(\cos \theta, \sin \theta)$

$2\pi$

$\pi$

$1$

$[-1, 1]$ or $-1 \leq y \leq 1$

All real numbers or $(−\infty, \infty)$

$\tan \theta = \frac{\sin \theta}{\cos \theta}$

Odd function: $\sin(-x) = -\sin x$

Even function: $\cos(-x) = \cos x$

At $\theta = \frac{\pi}{2} + k\pi$, where $k$ is an integer
