Secant :: Secant (a.) A right line drawn from the center of a circle through one end of a circular arc, and terminated by a tangent drawn from the other end; the number expressing the ratio line of this line to the radius of the circle. See Trigonometrical function, under Function..

Homography :: Homography (n.) A relation between two figures, such that to any point of the one corresponds one and but one point in the other, and vise versa. Thus, a tangent line rolling on a circle cuts two fixed tangents of the circle in two sets of points that are homographic..

Tangent :: Tangent (v. t.) A tangent line curve, or surface; specifically, that portion of the straight line tangent to a curve that is between the point of tangency and a given line, the given line being, for example, the axis of abscissas, or a radius of a circle produced. See Trigonometrical function, under Function..

Lemniscate :: Lemniscate (n.) A curve in the form of the figure 8, with both parts symmetrical, generated by the point in which a tangent to an equilateral hyperbola meets the perpendicular on it drawn from the center..

Cusp :: Cusp (n.) A multiple point of a curve at which two or more branches of the curve have a common tangent.

Tangentially :: Tangentially (adv.) In the direction of a tangent.

Bitangent :: Bitangent (n.) A line that touches a curve in two points.

Stress :: Stress (n.) The force, or combination of forces, which produces a strain; force exerted in any direction or manner between contiguous bodies, or parts of bodies, and taking specific names according to its direction, or mode of action, as thrust or pressure, pull or tension, shear or tangential stress..

Mesologarithm :: Mesologarithm (n.) A logarithm of the cosine or cotangent.

Level :: Level (n.) A horizontal line or plane; that is, a straight line or a plane which is tangent to a true level at a given point and hence parallel to the horizon at that point; -- this is the apparent level at the given point..

Indicatrix :: Indicatrix (n.) A certain conic section supposed to be drawn in the tangent plane to any surface, and used to determine the accidents of curvature of the surface at the point of contact. The curve is similar to the intersection of the surface with a parallel to the tangent plane and indefinitely near it. It is an ellipse when the curvature is synclastic, and an hyperbola when the curvature is anticlastic..

Asymptote :: Asymptote (n.) A line which approaches nearer to some curve than assignable distance, but, though infinitely extended, would never meet it. Asymptotes may be straight lines or curves. A rectilinear asymptote may be conceived as a tangent to the curve at an infinite distance..

Curvature :: Curvature (n.) The amount of degree of bending of a mathematical curve, or the tendency at any point to depart from a tangent drawn to the curve at that point..

Sector :: Sector (n.) A mathematical instrument, consisting of two rulers connected at one end by a joint, each arm marked with several scales, as of equal parts, chords, sines, tangents, etc., one scale of each kind on each arm, and all on lines radiating from the common center of motion. The sector is used for plotting, etc., to any scale..

Synclinal :: Synclastic (a.) Curved toward the same side in all directions; -- said of surfaces which in all directions around any point bend away from a tangent plane toward the same side, as the surface of a sphere; -- opposed to anticlastic..

Subtartarean :: Subtangent (n.) The part of the axis contained between the ordinate and tangent drawn to the same point in a curve.

Tangential :: Tangential (a.) Of or pertaining to a tangent; in the direction of a tangent.

Bitangent :: Bitangent (a.) Possessing the property of touching at two points.

Touch :: Touch (v. t.) To be tangent to. See Tangent, a..

Tangent :: Tangent (a.) Touching; touching at a single poin.
