👉 A torus, also known as a double-ended cylinder, is a curved surface that has two ends. The term "torus" comes from the Latin word "torus," which means "tube." It is an important concept in geometry and physics because it can be used to model many objects in everyday life. In mathematics, tori are often represented geometrically using parametric equations or as a function of two variables. For example, the equation for a circle centered at the origin (0
