This example dynamically demonstrates the graphs and properties of inverse trigonometric functions, intuitively showing their domains, ranges, and geometric meanings. It involves core concepts like inverse trigonometric functions, trigonometric graphs, geometric transformations, and continuity. The construction utilizes GeoGebra commands and objects such as Rotate, OrthogonalLine, Intersect, Circle, Ray, etc. Suitable for high school and above mathematics learners to understand the intuitive concepts and properties of inverse trigonometric functions.
