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{A d j a c e n t S i d e}{O p p o s i t e S i d e} \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}{T a n x} \end{array}

\begin{array}{l} \frac{C o s x}{S i n x} \end{array}

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
