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 triangle: Opposite is always opposite the angle. And Adjacent is always next to the angle.

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.

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.

Aug 27, 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 adjacent to that angle.

May 18, 2025 · Discover everything you need to know about tangent and cotangent functions in this concise guide. Learn definitions and properties.

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".

There are multiple formulas related to tangent function which can be derived from various trigonometric identities and formulas. Let us learn the tangent formulas along with a few solved examples.

Tangent (tan) function - Trigonometry (See also Tangent to a circle). In a right triangle, the tangent of an angle is the length of the opposite side divided by the length of the adjacent side.

Tangent trigonometric function.Tangent function tan (x), tangent function. Definition of tan Graph of tan Tan rules Inverse tangent function Tan table Tan calculator Tangent definition In a right triangle ABC the tangent of α, tan (α) is defined as the ratio betwween the side opposite to angle α and the side adjacent to the angle α: tan α = a / b Example a = 3" b = 4" tan α = a / b = 3 / ...
