Tangent of an angle is a ratio between the side opposite to the angle and the side adjacent to the angle.

Tangent

Tangent is one of three trigonometric functions of an angle.

Values and applications

tan(x) is found by calculating the ratio of two sides of a right-angled triangle, the opposite and the adjacent.
