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 …

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 …

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

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

A tangent touches a curve at exactly one point, while a secant crosses through a curve at two points. Think of a tangent as a gentle touch and a secant as a straight cut through the curve.

The word "tangent" comes from the Latin "tangere," meaning "to touch." Geometrically, the tangent is a line segment perpendicular to the x-axis, originating at point C and intersecting the extended side OP.

The tangent function, along with sine and cosine, is one of the three most common trigonometric functions. In any right triangle, the tangent of an angle is the length of the opposite side (O) divided …

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.
