Exploring trigonometric ratios on the unit circle
- David Wees
1. Drag point B around. While doing this, pick 10 or so points and record the values of the side lengths and the angles for the triangle. 2. Look at your data, and your observations while you were dragging the point around, and look for relationships between the sides and/or the angles. You may want to consider the sine, cosine, and tangent functions as well as other algebraic relationships between the different sides and angles.
