Sine, Cosine and Tangent - Math is Fun
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 triangle: Opposite is always opposite the angle. And Adjacent is always next to the angle.
Trigonometric functions - Wikipedia
The trigonometric functions most commonly used in modern mathematics are the sine, the cosine, and the tangent functions. Their reciprocals are respectively the cosecant, the secant, and the cotangent functions, which are less commonly used.
Tangent | Definition, Formulas, & Facts | Britannica
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 adjacent to that angle.

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.
Tangent — Definition, Formula & Examples - Mathwords
Tangent appears constantly in geometry, physics, and engineering whenever you need to relate vertical and horizontal distances. For example, if you know the angle of elevation to the top of a building and your distance from it, tangent lets you calculate the building's height.
Tangent in trigonometry made simple - Andrea Minini
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.
Tangent Meaning in Geometry - BYJU'S
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 such that the value of cosine function should not equal to zero.
