# $\sec{(0^°)}$ value

$\sec{(0^°)} \,=\, 1$

The value of secant in a zero degrees right triangle is called the secant of angle zero degrees.

## Introduction

The secant of angle zero degrees is a value, which represents the quotient of length of hypotenuse by the length of adjacent side when the angle of a right triangle is equal to zero degrees.

The secant of angle zero degrees is written as $\sec{(0^°)}$ in Sexagesimal system and the exact value of secant of angle zero degrees is equal to one. In trigonometric mathematics, it is written in the following form.

$\sec{(0^°)} \,=\, 1$

The secant of zero degrees can be expressed in two other mathematical forms in trigonometry.

### circular system

The secant of zero degrees is expressed as secant of zero radian in circular system. It is written as $\sec{(0)}$ mathematically in trigonometry.

$\sec{(0)} \,=\, 1$

### Centesimal system

The secant of angle zero degrees is also expressed as secant of angle zero grades. It is written in mathematical form as $\sec{(0^g)}$ in Centesimal system.

$\sec{(0^g)} \,=\, 1$

#### Proofs

The exact value of secant of zero degrees can be derived in mathematics in three distinct methods.
