# Quick Answer: What Is Cot In Math?

## What is cot in math equal to?

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.

## Is COT the same as cos?

The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x. The secant of x is 1 divided by the cosine of x: sec x = 1 cos x, and the cosecant of x is defined to be 1 divided by the sine of x: csc x = 1 sin x. = tan 5π 4. Thus, sec x and tan x have the same domains.

## What is cot on a calculator?

In trigonometry, the cotangent is the reciprocal of the tangent. The formula for determining the tangent is the opposite side divided by the adjacent side of a triangle. When inputting cotangent into a graphing calculator, you need to know the angle in degrees for which you are trying to find the cotangent.

## What is the correct definition for cot?

Answer Expert Verified Cotangent (in a right-angled triangle) the ratio of the side (other than the hypotenuse) adjacent to a particular acute angle to the side opposite the angle.

## Is COT the same as tan 1?

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.

## What is cot the opposite of?

Allied to these are the three reciprocal ratios, cosecant, secant and cotangent: cosecθ=hypotenuse opposite,secθ=hypotenuseadjacent, cot θ=adjacent opposite.

## Is SEC the 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.

## What is SEC Cosec and cot?

Secant ( sec ) is the reciprocal of cosine (cos) Cosecant ( cosec ) is the reciprocal of sin. Cotangent ( cot ) is the reciprocal of tan.

## Does Tan equal Y X?

The unit circle definition is tan (theta)= y / x or tan (theta)=sin(theta)/cos(theta). The tangent function is negative whenever sine or cosine, but not both, are negative: the second and fourth quadrants. Tangent is also equal to the slope of the terminal side. Like we have for the sine and cosine.

## 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.
