Spherical Coordinates GeoGebra Example

This example demonstrates the plotting and visualization of 3D surfaces in spherical coordinates. Key math concepts include spherical coordinates, 3D surfaces, parametric equations, and symmetry. Construction highlights: the Surface command is used to draw the surface, with parameters ρ, r, z_1, a for parametrization. Suitable for high school students and math enthusiasts learning applications of spatial geometry and parametric equations.
