Understanding Torus Parameterization

The video tutorial explains how to parameterize a torus using two parameters, s and t. It covers the visualization of the torus in 3D space, the calculation of z, x, and y coordinates using trigonometry, and the formulation of a position vector-valued function. The tutorial emphasizes the importance of visualization in understanding the parameterization process.
