Tractrix is a type of curve used in various fields, including physics, engineering, and acoustics. Mathematically, a tractrix is defined as the curve that is generated by a point moving in such a way that its tangent always approaches a fixed point (the focus) at a constant distance. This distance is typically referred to in the context of the curve's asymptote.
