Tangent may also refer to:


  • 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
    • Bitangent, a line that is tangent to two different curves, or tangent twice to the same curve
  • The tangent function, one of the six basic trigonometric functions
