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 …

The meaning of TANGENT is an abrupt change of course : digression. How to use tangent in a sentence.

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 graph of tangent is periodic, meaning that it repeats itself indefinitely. Unlike sine and cosine however, tangent has asymptotes separating each of its periods.

Nov 20, 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 …

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".

Idiom go off on a tangent (Definition of tangent from the Cambridge Advanced Learner's Dictionary & Thesaurus © Cambridge University Press)

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 extended side OP.

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 represented as ratios of …

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) divided …
