Rotation FNS about yAxis: Surface Function Analogue

This example demonstrates the generation of a 3D surface of revolution from a 2D function, illustrating how rotating a function around the y-axis creates a surface. Core math concepts include rotation, surfaces, trigonometric functions, and function graphing. It uses GeoGebra's Surface and Rotate commands with objects f (function), n (rotation count), a (angle), and f_1 (initial function). Suitable for high school and above students studying 3D geometry, function transformations, and surface generation applications.
