C1 noun 正式

cotangency

/koʊˈtændʒənsi/

Cotangency is a geometric property describing the state of two curves or surfaces that touch each other at a single point and share a common tangent line or plane at that point. It implies that the slopes or derivatives of the curves are identical at the point of contact without the curves necessarily crossing one another.
