What does Tan mean in mathematics?
Tangent value in right-angled trigonometric function.

Tan is the tangent value in the right-angled trigonometric function, which refers to the ratio of the opposite side to the adjacent side in the trigonometric function. In rectangular coordinate system, the formula is tan θ = y/x.

The base of a right triangle is x, the height is y, the hypotenuse is z, and the angle between the base and hypotenuse is a ... Tan is generally correct. In Rt△ABC (right triangle), ∠C = 90, AB is the opposite side C of ∠ C, BC is the opposite side A of ∠A, AC is the opposite side B of ∠B, and the tangent function is tanB=b/a, that is, tanB=AC/BC.
