Point of rectification

From Encyclopedia of Mathematics
Jump to: navigation, search

A point on a curve at which the curvature vanishes. At a point of rectification, the deviation of the curve from the tangent line is at least of order three. If at a point of rectification the curve passes through its tangent line from one side to the other, then the point of rectification is a point of inflection.
