Look at an explanation of the trigonometric ratios: sine, cosine and tangent. Adjust the angles of a right angle triangle within a unit circle (radius of one unit). Identify the cosine ratio and enter the cosine values of angles from 0–90 degrees into a table. Answer questions about the cosine values. This learning object is one in a series of ten objects.
1. Students explore the unit circle definition of trigonometric ratios.
2. Students use a unit circle model to determine values of trigonometric ratios.
