Tangent Function Evaluator

Understanding Tangent (tan)

The tangent function, denoted as $$tan({x})$$, is a fundamental trigonometric function. In a right-angled triangle, the tangent of an angle is the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.

Mathematically, $$tan({x}) = rac{{sin({x})}}{{cos({x})}}$$. The tangent function has a period of $$\pi$$, and it is undefined at $$x = rac{{\pi}}{2} + n\pi$$, where n is an integer, due to cosine being zero at these points.

Radians are a unit of angular measure, where $$2\pi$$ radians is equal to 360 degrees. This tool accepts angles in radians for calculating the tangent value.

Use this Tangent Calculator to quickly evaluate the tangent of any angle provided in radians and visualize its behavior on the graph. The interactive graph allows you to explore how the tangent function changes with different angle values.
