Quadric Surfaces

This example demonstrates the geometric shapes of quadric surfaces, which are surfaces in three-dimensional space defined by quadratic equations, including ellipsoids, hyperboloids, and paraboloids. By adjusting parameters a, b, and c, you can observe the changes in the shapes of these surfaces. The example uses GeoGebra objects a, b, c, and equation eq1 to construct these surfaces. Suitable for high school mathematics education and learning three-dimensional geometry.
