Graphs of Sine and Cosine from Unit Circle for One Period

This example demonstrates the graphs of sine and cosine functions within one period using the unit circle. It involves core trigonometric concepts and dynamically shows the changes in sine and cosine values by constructing the intersection of circle arcs and circles. Commands used include Intersect, Circle, and CircleArc. Suitable for high school mathematics education and learning the properties of sine and cosine functions.
