MAFS.912.F-TF.1.2 – Explain how the unit circle in the coordinate plane enables the extension of trigonometric functions to all real numbers using radian measures of angles traversed counterclockwise around the unit circle.
- The benchmark will be assessed using Equation Response, Graphic Response, Hot Spot Response, Movable Text Response, Selectable Text Response or Open Response.
- Items may require students to: find arc length or sector area based on radian measures; convert radian measure to degree measure and vice versa; or prove the Pythagorean identity.
- Trig ratios are limited to sine or cosine.
