rectifying line

用法例句

,we know that a curve lies in a plane if its position vector lies in its osculating plane at each point, and lies on a sphere if its position vector lies in its normal plane at each point;In this paper,we mainly discuss the rectifying curves in three dimensional Minkowski space.
