## What is SEC on a calculator?

Description. **Secant** function. **SEC**(x) returns the **secant** of x. To convert degrees to radians you use the RADIANS function.

## What is SEC trig function?

Secant (**sec**) – **Trigonometry function**

In a right triangle, the secant of an angle is the length of the hypotenuse divided by the length of the adjacent side. In a formula, it is abbreviated to just ‘**sec**‘. In fact, most calculators have no button for them, and software **function** libraries do not include them.

## What is Secant formula?

Calculate **secant** by finding the reciprocal of the cosine of an angle. For the cos A and cos B in Step 3, the reciprocals are 1/cos A and 1/cos B. So **sec** A = 1/cos A and **sec** B= 1/cos B. Express **secant** in terms of the sides of the right triangle by substituting cos A =b/c into the **secant equation** for A in Step 4.

## What does Secant stand for?

**Secant** is a term in mathematics derived from the Latin secare (“to cut”). It may refer to: a **secant** line, in geometry. the **secant** variety, in algebraic geometry. **secant** (trigonometry) (Latin: secans), the multiplicative inverse (or reciprocal) trigonometric function of the cosine.

## Is SEC opposite of Cos?

The secant ( **sec** ) (**sec**) (**sec**)

The secant is the reciprocal of the **cosine**. It is the ratio of the hypotenuse to the side adjacent to a given angle in a right triangle.

## Is Tan 1 the same as cot?

Using the **tan**^{–}** ^{1}**x convention may lead to confusion about the difference between arctangent and

**cotangent**. It turns out that arctan and

**cot**are really separate things:

**cot**(x) =

**1**/

**tan**(x), so

**cotangent**is basically the reciprocal of a

**tangent**, or, in other words, the multiplicative

**inverse**.

## Is sin 1 the same as CSC?

cosecant is the reciprical of the **sin** function or **1**/**sin**(x) so that **csc**(x)***sin**(x) = **1** when it is defined. The two can be confused since arcsin(x) is often denoted as **sin**^-**1**(x) and x^-**1** is **1**/x. The cosecant is the reciprocal of the **sine**; the arcsin of x is the angle whose **sine** is x.

## What is the reciprocal of SEC?

There are three **reciprocal** trigonometric functions, making a total of six including cosine, sine, and tangent. The **reciprocal** cosine function is **secant**: **sec**(theta)=1/cos(theta). The **reciprocal** sine function is cosecant, csc(theta)=1/sin(theta).

## What are the six basic trigonometric functions?

There are six **trigonometric ratios**, sine, **cosine**, **tangent**, **cosecant**, **secant** and **cotangent**. These six **trigonometric ratios** are abbreviated as **sin**, **cos**, tan, **csc**, **sec**, cot.

## What is trigonometry formula?

Basic **Trigonometric** Function **Formulas**

By using a right-angled triangle as a reference, the **trigonometric** functions or **identities** are derived: sin θ = Opposite Side/Hypotenuse. cos θ = Adjacent Side/Hypotenuse. tan θ = Opposite Side/Adjacent Side.

## What does cot mean in math?

more The short name for **cotangent**. It is the length of the adjacent side divided by the length of the side opposite the angle in a right-angled triangle. **cot**(θ) = adjacent / opposite.

## What does cot mean in trigonometry?

In a right angled triangle, the **cotangent** of an angle **is**: The length of the adjacent side divided by the length of the side opposite the angle. The abbreviation **is cot**. **cot**(θ) = adjacent / opposite. It **is** not commonly used, and **is** equal to 1/tangent.
