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 …

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.

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

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 …

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

Discover how the derivative of a function reveals the slope of the tangent line at any point on the graph. We'll explore how to use this powerful tool to determine the equation of the tangent line, …

In trigonometry, the tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side. In other words, it is the ratio of sine and cosine function of an acute angle …

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 …

The tangent function, often denoted as 'tan,' is a fundamental concept in trigonometry. It's a function that connects the angles of a right triangle to the ratios of its sides.
