Learning Objectives

After completing The Unit Circle, you will

• understand and be familiar with the shape and four quadrants of the unit circle

• understand, recognize and be able to read the angles of the unit circle in both degrees and radians

• will know and recognize the main x-values and y-values of the unit circle

• be able to recognize the three unique right triangles within the unit circle

• be able to match the unique right triangles with their corresponding x-values and y-values

• be able to recognize the unique x-values and y-value pairings of the unit circle

The Unit Circle will become your greatest tool in being able to succeed in your Pre-Calculus and Trigonometry course so do your due diligence to try and retain as much information related to it as possible.
