Envelop :: Envelop (n.) A curve or surface which is tangent to each member of a system of curves or surfaces, the form and position of the members of the system being allowed to vary according to some continuous law. Thus, any curve is the envelope of its tangents..

Tractrix :: Tractrix (n.) A curve such that the part of the tangent between the point of tangency and a given straight line is constant; -- so called because it was conceived as described by the motion of one end of a tangent line as the other end was drawn along the given line.

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..

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

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..

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..

Semitangent :: Semitangent (n.) The tangent of half an arc.

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..

Tangental :: Tangental (a.) Tangential.

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

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..

Tangent :: Tangent (a.) meeting a curve or surface at a point and having at that point the same direction as the curve or surface; -- said of a straight line, curve, or surface; as, a line tangent to a curve; a curve tangent to a surface; tangent surfaces..

Shear :: Shear (v. t.) An action, resulting from applied forces, which tends to cause two contiguous parts of a body to slide relatively to each other in a direction parallel to their plane of contact; -- also called shearing stress, and tangential stress..

Cotangent :: Cotangent (n.) The tangent of the complement of an arc or angle. See Illust. of Functions.

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..

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

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

Tangency :: Tangency (n.) The quality or state of being tangent; a contact or touching.

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..

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..
