# Cotangent Formula

If the length of the adjacent gets divided by the length of the opposite side, it becomes the Cotangent of an angle in a right triangle.

We write it as ‘Cot’

## Cot Formula

 Cot X = $$\begin{array}{l}\frac{Adjacent Side}{Opposite Side}\end{array}$$

Out of the six trigonometric functions, Secant, cotangent, and cosecant are barely used.

## What is Cot x formula?

Cotangent is the reciprocal of tan, Cot x =

$$\begin{array}{l}\frac{1}{Tanx}\end{array}$$
=
$$\begin{array}{l}\frac{Cos x}{Sin x}\end{array}$$

## Cotangent theta Formula Questions

Example 1: Find Cot X if tan x = 5/6

Solution: As cot X = 1/ tanX

=1/5/6

= 6/5

So, Cot X = 6/5
