Mathematical Definition

In trigonometry, the tangent function is defined as the ratio of the opposite side to the adjacent side in a right-angled triangle. For an angle θ measured from the positive x-axis, the tangent is given by:

tan θ = opposite / adjacent

For the angle 2π/3, the opposite side has a length of √3, and the adjacent side has a length of 1. Therefore, the tangent of 2π/3 is:
