Definition of tractrix in English:

tractrix

nounPlural tractrices ˈtraktrɪksˈtræktrɪks

Geometry

1A curve whose tangents all intercept the x-axis at the same distance from the point of contact, being the involute of a catenary.
〔几何〕曳物线，等切面曲线
Example sentencesExamples
- Among the properties of the tractrix are the fact that the length of a tangent from its point of contact to an asymptote is constant.
1. 1.1 One of a class of curves similarly traced by one end of a rigid rod, whose other end moves along a fixed line or curve.
  曳物线
  Example sentencesExamples
  The concrete realisation uses the pseudosphere, a surface generated by the revolution of a tractrix about its asymptote.
  The tractrix is sometimes called a tractory or equitangential curve.
  The model was obtained on the surface of revolution of a tractrix about its asymptote.

Origin

Early 18th century: modern Latin, feminine of late Latin tractor 'that which pulls' (see tractor).
