The trigonometric functions most widely used in modern mathematics are the sine, the cosine, and the tangent functions. Their reciprocals are respectively the cosecant, the secant, and the cotangent …

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.

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.

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 adjacent to that angle.

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

Jul 23, 2025 · Tangent of an angle in a right-angled triangle is the ratio of the length of the opposite side to the length of the adjacent side to the given angle. We write a tangent function as "tan".

This page explains the sine, cosine, tangent ratio, gives on an overview of their range of values and provides practice problems on identifying the sides that are opposite and adjacent to a given angle.

Tangent in geometry is defined as a line or plane that touches a curve or a curved surface at exactly one point. Learn about tangent definition along with properties and theorems.

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 …
