The tan function is undefine at 90 degrees because division by zero is not possible. The adjacent side of a right triangle would be zero.
Tangent Function
Tangent Function: Trigonometric function tan(x) is called a tangent function it is one of the main six trigonometric functions and is generally written as tan x. The tangent function is the ratio of the opposite side and the adjacent side of the angle in consideration in a right-angled triangle.
In this article, we will learn about Tangent function definition, Tangent function graph, tangent function values, examples, and others in detail.
