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

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 side …

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 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 main body …

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 …

One of the trigonometry functions. In a right triangle, the tangent of an angle is the opposite side over the adjacent side. For more on this see Trigonometry tangent function.

off on or at a tangent, digressing suddenly from one course of action or thought and turning to another.

A tangent touches a curve at exactly one point, while a secant crosses through a curve at two points. Think of a tangent as a gentle touch and a secant as a straight cut through the curve.
