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.

Jan 2, 2026 · 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 …

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

We were talking about exercise and got off on a tangent. A tangent is also a line that touches a curve or solid at a particular point. This is a novel with many tangents, little streams flowing off …

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 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 …

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 …

Dec 8, 2025 · Tangent, which is commonly abbreviated to three letters as T-A-N, is the ratio of the side opposite the angle we know, or want to know, over the side adjacent to that angle.
