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 …

What is tangent? In the context of a triangle, the tangent function is the ratio of the opposite side to the adjacent side. For an angle $\alpha$, the tangent function is denoted by $\tan \alpha$. …

In Geometry, the tangent is defined as a line touching circles or an ellipse at only one point. Suppose a line touches the curve at P, then the point “P” is called the point of tangency. In …
