The Cos-Sin Calculator is a device that teaches the relationship between a right triangle and the trigonometric functions. It increases the level of learning to a higher level as described in Bloom's Taxonomy. Most people learn at the first level of learning by just remember facts. For example, a person might have remembered that y = r sin θ and they might be able to draw a sin curve. But they might not be able to calculate the sin function without the use of a table or calculator. The second level of learning is understanding concepts. The Cos-Sin Calculator shows how to calculate the trigonometric functions using the ratios of the sides of a right triangle. You can physically see this and understand the relationships. And this brings the students to a higher level of learning.
