<font face="Times New Roman" size="+2">


Amplitude: 1  Radius of the unit circle
Period:  *[tex \Large 2\pi]  Circumference of the unit circle
Domain:  *[tex \Large \left\{\theta\ :\ \theta\ \in\ \mathbb{R}\right\}]  Range of values of the angle between the positive *[tex \Large x]-axis and the terminal ray
Range:  *[tex \Large \left\{y\ \in\ \mathbb{R}\ :\ -1\ \leq\ y\ \leq\ 1\right\}]  Maximum and minimum values of the *[tex \Large y]-coordinate of any point on the unit circle 
x-intercepts:  *[tex \Large \left\{\(k\pi,\,0)\ :\ k\ \in \mathbb{Z}\right\}] values of *[tex \Large \theta] for which the *[tex \Large y]-coordinate of the point on the unit circle is zero.
