The graph of tangent is periodic, meaning that it repeats itself indefinitely. Unlike sine and cosine however, tangent has asymptotes separating each of its periods.

Sine, Cosine and Tangent are the main functions used in Trigonometry and are based on a Right-Angled Triangle. Before getting stuck into the functions, it helps to give a name to each side of …

In geometry, the tangent line (or simply tangent) to a plane curve at a given point is, intuitively, the straight line that "just touches" the curve at that point.

The meaning of TANGENT is an abrupt change of course : digression. How to use tangent in a sentence.

Nov 20, 2025 · The tangent is one of the six fundamental trigonometric functions in mathematics. In a right triangle, it is the ratio of the length of the side opposite a given angle to the length of …

Idiom go off on a tangent (Definition of tangent from the Cambridge Advanced Learner's Dictionary & Thesaurus © Cambridge University Press)

One of the trigonometry functions. In a right triangle, the tangent of an angle is the opposite side over the adjacent side. For more on this see Trigonometry tangent function.

As the ratio of the sine and cosine functions that are particular cases of the generalized hypergeometric, Bessel, Struve, and Mathieu functions, the tangent function can also be …

A tangent in maths is a straight line that touches a curve or circle at exactly one point, called the point of contact or tangency, without crossing the curve at that location.

Tangent is a fundamental trigonometric ratio defined as the ratio of the length of the side opposite an angle in a right triangle to the length of the adjacent side. It is a critical concept in …
