How to Use LaTeX Secant Symbol

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

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

Symbol Overview

Symbol: Secant

Unicode: U+221D

Type: Trigonometric

Package Requirement: None (built-in symbol)

Argument: None (no additional arguments needed)

LaTeX Command: \sec

Example: sec


The Secant 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 secant functions which is widely used in geometry, physics, and other scientific fields.


The LaTeX command \sec is used to display the Secant symbol.


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

Using the Secant Symbol to Calculate the Secant of an Angle

$\sec (60^\circ) = 2$

Output: 👇️

sec(60) = 2

In the above example, the secant symbol is used to calculate the secant of the angle 60 degrees, which is equal to 2.

Using the Secant Symbol in Trigonometric Equation

$\sec(x) = \frac{1}{\cos(x)}$

Output 👇️

sec(x) = 1 / cos(x)

In the above example, the secant symbol represents the relationship between the secant, and cosine functions in trigonometric.


The secant 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 secant symbol help you. The secant symbol (cos) is a fundamental trigonometric functions used extensively in mathematics and widely used in LaTeX documents.

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