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 …

What is Tangent Function? 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 …

Nov 3, 2025 · 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 …

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 …

Jul 23, 2025 · Tangent function, also called the tan (x), is a trigonometric function that takes the ratio of the side opposite to the angle being considered in a right-angled triangle to its adjacent …

Tangent, written as tan⁡ (θ), is one of the six fundamental trigonometric functions. Tangent, like other trigonometric functions, is typically defined in terms of right triangles and in terms of the …

Feb 24, 2025 · Trigonometric functions, also known as ‘ circular functions,’ are the ratio between any two sides of a right triangle: the opposite side, the adjacent side, and the hypotenuse with …

What is the tangent function in trigonometry? In trigonometry, the tangent function (tan) of an angle in a right triangle is the ratio of the opposite side to the adjacent side.

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

This video shows how to graph the Tangent function on the coordinate plane using the unit circle, how to determine the domain and range of the tangent function.
