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 a right …

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

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

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 the side …

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

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.

The tangent function is one of the main six trigonometric functions and is generally written as tan x. It is the ratio of the opposite side and the adjacent side of the angle in consideration in a right-angled …

5 days ago · The tangent function is defined by tanx= (sinx)/ (cosx), (1) where sinx is the sine function and cosx is the cosine function. The notation tgx is sometimes also used (Gradshteyn and Ryzhik …

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 trigonometry and …
