Patterns in the Unit Circle

In this assessment, students investigate patterns in the unit circle, namely patterns in the value of the three major trigonometric rations (sine, cosine, and tangent) in the four quadrants of the unit circle. By the end of the assessment, students are able to write a general formula for each of these three trigonometric ratios.
