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 …

Tangent. Tangent, written as tan⁡(θ), is one of the six fundamental trigonometric functions. Tangent definition. Tangent, like other trigonometric functions, is typically defined in terms 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. Leibniz defined it as the line through a …

: the trigonometric function that for an acute angle is the ratio between the leg opposite to the angle when it is considered part of a right triangle and the leg adjacent.

Aug 3, 2023 · The tangent of a circle is defined as a straight line that touches the circle at a single point. The point where the tangent touches the circle is called the ‘point of tangency’ or the …

May 28, 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 …

In trigonometry, the tangent function is used to find the slope of a line between the origin and a point representing the intersection between the hypotenuse and the altitude of a right triangle. …

Jan 10, 2025 · The word “tangent” comes from “tangens”, meaning touching or extending (the line that touches the circle at one point). The term “tangent” referring to an angle was first used by …

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 …

On the previous page, we examined how the sine and cosine ratios for right triangles can be expanded, via the unit circle, to being full-fledged graphable functions. The next trigonometric …
