 # What Is The Cotangent Of 30?

## What is the value of cot 30?

The exact value of cot(30) is √3 ..

## What is Sinπ?

The exact value of sin 180 is zero. Sine is one of the primary trigonometric functions which helps in determining the angle or sides of a right-angled triangle. … If theta is an angle, then sine theta is equal to the ratio of perpendicular and hypotenuse of the right triangle. To be noted the value of sin 0 is also 0.

## Is COT the same as tan 1?

Defining tan -1(x) and cot -1(x) For any x, tan -1(x) is the angle measure in the interval (- /2 , /2) whose tangent value is x. For any x, cot -1(x) is the angle measure in the interval (0 , ) whose cotangent value is x.

## What is the exact value of cos 30?

Cos 30° = √3/2 is an irrational number and equals to 0.8660254037 (decimal form). Therefore, the exact value of cos 30 degrees is written as 0.8660 approx. √3/2 is the value of Cos 30° which is a trigonometric ratio or trigonometric function of a particular angle.

## How do you find the cotangent of a triangle?

The cotangent of an angle in a right triangle is a relationship found by dividing the length of the side adjacent to the given angle by the length of the side opposite to the given angle. This is the reciprocal of the tangent function.

## Is tan 90 undefined or infinity?

Why is Tan 90 undefined? As we have got the result as infinity, and we cannot define infinity, therefore tan 90 is undefined.

## What is sin1 value?

0.8414709848The value of sin 1 is 0.8414709848, in radian. In trigonometry, the complete trigonometric functions and formulas are based on three primary ratios, i.e., sine, cosine, and tangent in trigonometry.

## What is the Cotangent equal to?

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 .

## What does cot mean?

small usually collapsible bed1 : a small usually collapsible bed often of fabric stretched on a frame. 2 British : crib sense 2b. cot. abbreviation.

## What is Sinx COSX?

sinx+cosx=sinx±√1−sin2x.

## Why is tan 90 undefined?

At 90 degrees we must say that the tangent is undefined (und), because when you divide the leg opposite by the leg adjacent you cannot divide by zero. In the third quadrant the hypotenuse extended will now meet the tangent line above the x-axis and is now positive again.

## What tangent is 45 degrees?

So the tangent of 45 degrees is 1. Keep in mind I am in high school at the time so this will be a very basic answer. I use the unit circle to remember all of these common answers. Sin X= b/r, cos X= a/r, making tan X=sin X/ cos X or (b/r)*(r/a)= b/a.

## Where is Cos undefined?

Sine and cosine functions are never undefined on unit circle. They are defined at every point of a unit circle. Because according to definitions of Sine and cosine, cosine is the x-coordinate of a point moving along unit circle. Likewise, Sine is the y-coordinate of that moving point.

## 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.

## What is the COT pi?

cot(π) = 1. Tan(π)
