Tangent may refer to:

In mathematics:

  • A tangent, in geometry, is a straight line through a point on a curve that has the same direction at that point as the curve.
    • There are analogous concepts for surfaces and higher-dimensional smooth manifolds, such as the tangent space.
    • More generally, in geometry, two curves are said to be tangent when they intersect at a given point and have the same direction at that point; see for instance tangent circles.
    • A bitangent is a line that is tangent to two different curves, or tangent twice to the same curve.
  • In trigonometry, the tangent function is one of the six basic trigonometric functions
