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

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 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 …

The tangent function is defined by determining the ratio of the length of the side opposite a reference angle (acute angle) of a right triangle to the length of the adjacent side of a right …

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) …

Dec 3, 2025 · The tangent function is defined by tanx= (sinx)/ (cosx), (1) where sinx is the sine function and cosx is the cosine function. The notation tgx is sometimes also used (Gradshteyn …
