I am writing a lesson on the unit circle and I understand its various properties concerning the trigonometric functions (ie. the sin of an angle is equal to the y coordinate of the point at which the terminal side of the angle intersects with the circle). However what other unique features does the unit circle exhibit? How else can it be used in a lesson? Where is the usefullness of the unit circle applied in practical applications?
Thank You for all your help in advance!

The unit circle provides you with the Sin, Cos, and Tan of all the most importan angles in Degrees or radians. If you are familiar with the unit circle you can find the Sin, Cos, Tan, Sec, Csc or Cot of almost any angle.

Hi. By having a unit less diameter (well, 1 of anything) all sides have the same unit length. This makes understanding the underlying principle easier.
