Modifiable Torus Explorer

This example demonstrates how to dynamically visualize a modifiable torus by adjusting parameters R, r, and a. It involves core math concepts like Calculus, Angles, Expected Value, Tangent Function, Pie Chart or Circle Chart, and Real Numbers. The construction uses the GeoGebra command Surface and Slider objects to manipulate the parameters. Suitable for high school and above students exploring solid geometry and calculus.
