How to Use LaTeX Cotangent Symbol

To write the Cotangent (cot) in LaTeX, use the LaTeX command \cot. It will add cot symbol in the text.

In this article, we will discuss how to use cotangent (cot) in the LaTeX document and its applications in trigonometric calculations and mathematical concepts.

Symbol Overview

Symbol: Cotangent

Unicode: U+2212

Type: Trigonometric

Package Requirement: None (built-in symbol)

Argument: None (no additional arguments needed)

LaTeX Command: \cot

Example: cot


The Cotangent is a built-in symbol available in LaTeX, and one of the fundamental trigonometric functions used in mathematics to related angles to the sides of a right-angled triangle.

It is commonly used to represent contangent functions which is widely used in geometry, physics, and other scientific fields.


The LaTeX command \cot is used to display the Cotangent symbol.


Let’s understand using Cotangent symbol in various domains like mathematics, trigonometry with the help of examples.

Using the Cotangent Symbol to Calculate the cotangent of an Angle

$\cot (45^\circ) = 1$

Output: 👇️

cot(45) = 1

In the above example, the cotangent symbol is used to calculate the tangent of the angle 45 degrees, which is equal to 1.

Using the Cotangent Symbol in Trigonometric Equation

$\cot(x) = \frac{1}{\tan(x)}$

Output 👇️

cot(x) = 1 / tan(x)

In the above example, the tangent symbol represents the relationship between the cotangent, and tangent functions in trigonometric.


The tangent symbol has numerous applications in LaTeX documents such as:

  • Calculate angles and sides in the right-angled triangles.
  • Solve trigonometric equations and identities.


I hope the above article on how to use cotangent symbol help you. The cotangent symbol (cot) is a fundamental trigonometric functions used extensively in mathematics and widely used in LaTeX documents.

By effiectively use the the cotangent symbol in LaTeX documents to convey accurate and precise trigionometric calculations and mathematical concepts.
