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