The Trig Rectangles
The first design is intended for students to discover and derive the sum formulas for sine and cosine, while the second design allows for the discovery of the difference formulas for sine and cosine. Both designs engage the student in a mathematical experience in which they utilize prior knowledge to form connections and discover new ideas. These two tools provide a concrete visual representation of abstract mathematical concepts.
