Trigonometry

The Unit Circle is an important tool that helps visualize trigonometric ratios and more. This topic explores how to measure Angles on the Unit Circle and find Coordinates on the Unit Circle. Drawing Triangles on the Unit Circle is a useful strategy for evaluating trigonometric functions in both radians and degrees. From Finding the Reference Angle to Plotting a Point on the Unit Circle, you will see how essential the Unit Circle is when studying trigonometry.
