Trigonometric Function Graphs

This example demonstrates the graphs of trigonometric functions, including sine, cosine, tangent, cotangent, secant, and cosecant. Using GeoGebra commands such as Circle, Point, Angle, Polygon, Segment, Line, Intersect, OrthogonalLine, CircleArc, and Function, it shows the periodicity, symmetry, and special points of these functions. Suitable for high school mathematics education and learning trigonometric function graphs.
