Vectors on the Unit Circle

This example dynamically illustrates vector addition and subtraction on the unit circle, allowing users to drag points on the circle to observe how vectors change. Core mathematical concepts include the unit circle, vectors, vector addition/subtraction, and their geometric interpretations. Construction uses GeoGebra commands: Circle to create the unit circle, Point to place movable points on the circle, Vector to define vectors, and text objects to display coordinates or results. Suitable for high school or early college students learning vector basics, trigonometric identities, or complex number representations, and for teachers demonstrating vector operations visually.
