Revolution Volume Integration Demo

① This example dynamically displays a solid of revolution formed by rotating a plane curve around an axis, and visually demonstrates the volume calculation via integration. ② Core mathematical concept: definite integral applied to volumes of revolution (disk/washer or shell method), involving integration variables, bounds, and accumulation of volume elements. ③ Construction: uses GeoGebra commands CurveCartesian to define the generating curve and Surface to create the rotated surface; sliders control rotation angle or curve parameters to animate the volume; objects a–n likely include curve equations, axis, integration interval, and computed volume values. ④ Suitable for high school advanced or college calculus courses, for classroom demonstrations or student exploration of volume by integration.
