[ noun ] (mathematics,geometry) a straight line or plane that touches a curve or curved surface at a point but does not intersect it at that point
Used in print (R. P. Jerrard, "Inscribed squares in plane curves"...)Any other point_of_intersection between C and **f will be called a tangent point . Thus **f is also continuous at **f , and in a neighborhood of **f which does not contain a tangent point . We turn now to the set of tangent points on the graph . The fact that there can not be any limit_points of the set except in closed_intervals follows from the argument used in Lemma 1 , namely , that near any tangent point in the C-plane the curves C and **f are analytic , and therefore the difference between them must be a monotone function in some neighborhood on either side of the tangent point . The fact that there can not be any limit_points of the set except in closed_intervals follows from the argument used in Lemma 1 , namely , that near any tangent point in the C-plane the curves C and **f are analytic , and therefore the difference between them must be a monotone function in some neighborhood on either side of the tangent point .
