Tractrix

by Jesse Russell (Editor)

High Quality Content by WIKIPEDIA articles! Tractrix (from the Latin verb trahere "pull, drag"; plural: tractrices) is the curve along which a small object moves, under the influence of friction, when pulled on a horizontal plane by a piece of thread and a puller that moves at a right angle to the initial line between the object and the puller at an infinitesimal speed. It is therefore a curve of pursuit. It was first introduced by Claude Perrault in 1670, and later studied by Sir Isaac Newton (1676) and Christian Huygens (1692).
