what is tangent

Let us learn what is tangent?

-->

The line which meet the another line at the common point is said to be as tangents. The trigonometric work (function) of an acute angle in an right angled triangle that is the ratio of the length of the opposite side & the ratio of the length of the adjacent side. A plane or a straight line which touches a curved surface at a point but it does not intersect at that point.

The function of tangent is used to calculate the ratio of sides of the triangle. It is also called as circular function. Tan is a one kind of trigonometric functions. Tan of an angle is the ratio of length of the opposite side is divided into adjacent. The definition of tan is the reciprocal of cot

Solve tangent Problem:
Find the function value of tan 25^o.
Use the tangent function identity to solve the problem.
tan x = cot(90^o – x)
tan 25^o = cot (90^o – 25^o )
= cot (65^o)
tan 25^o = 2.1445
The tangent of 25^o is 2.1445
