Samuel Johnson's Dictionary

  1. Tangentnoun

    Tangent, in trigonometry, is a right line perpendicularly raised on the extremity of a radius, and which touches a circle so as not to cut it; but yet intersects another line without the circle called a secant that is drawn from the centre, and which cuts the arc to which it is a tangent. Antoine Furetière

    Etymology: tangent, Fr. tangens, Lat.

    Nothing in this hypothesis can retain the planets in their orbs, but they would immediately desert them and the neighbourhood of the sun, and vanish away in tangents to their several circles into the mundane space. Richard Bentley, Serm.

Wikipedia

  1. Tangent

    In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point. Leibniz defined it as the line through a pair of infinitely close points on the curve. More precisely, a straight line is said to be a tangent of a curve y = f(x) at a point x = c if the line passes through the point (c, f(c)) on the curve and has slope f'(c), where f' is the derivative of f. A similar definition applies to space curves and curves in n-dimensional Euclidean space. As it passes through the point where the tangent line and the curve meet, called the point of tangency, the tangent line is "going in the same direction" as the curve, and is thus the best straight-line approximation to the curve at that point. The tangent line to a point on a differentiable curve can also be thought of as a tangent line approximation, the graph of the affine function that best approximates the original function at the given point.Similarly, the tangent plane to a surface at a given point is the plane that "just touches" the surface at that point. The concept of a tangent is one of the most fundamental notions in differential geometry and has been extensively generalized; see Tangent space. The word "tangent" comes from the Latin tangere, "to touch".

  1. tangent

    In mathematics, a tangent is a line or plane that touches a curve, surface, or sphere at a single point, but if extended, doesn't cross it. In trigonometry, tangent is a basic function to describe a ratio of the length of the side opposite to the angle to the length of the adjacent side in a right-triangle. In general terms, 'tangent’ can also refer to something hardly or indirectly related, or a completely different line of thought or action. For instance, in a conversation or a discussion, going off on a tangent means digressing from the main subject or theme to discuss a different topic.

Webster Dictionary

  1. Tangentverb

    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

  2. Tangentadjective

    touching; touching at a single point

  3. Tangentadjective

    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
