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 …

In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are functions of an angle. They relate the angles of a triangle to the …

Hence, the domain of tan x is all real numbers except the odd multiples of π/2. Now, the range of the tangent function includes all real numbers as the value of tan x varies from negative infinity …
