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 …

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 …

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 …

The tangent function, along with sine and cosine, is one of the three most common trigonometric functions. In any right triangle, the tangent of an angle is the length of the opposite side (O) …

As the ratio of the sine and cosine functions that are particular cases of the generalized hypergeometric, Bessel, Struve, and Mathieu functions, the tangent function can also be …

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 …

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 …
