 # Quick Answer: What Is Cot On A Calculator?

## What is the COT of 0?

Trigonometry Examples The exact value of arccot(0) is π2 .

The cotangent function is positive in the first and third quadrants.

To find the second solution, add the reference angle from π to find the solution in the fourth quadrant..

## 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.

## What is the value of cot pi by 2?

The exact value of cot(π2) cot ( π 2 ) is 0 .

## Is COT the same as 1 tan?

tan x−1, sometimes interpreted as (tan(x))−1 = 1tan(x) = cot(x) or cotangent of x, the multiplicative inverse (or reciprocal) of the trigonometric function tangent (see above for ambiguity)

## What does cot mean in math?

cotangentThe 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. (Note: the tangent function tan(θ) = opposite / adjacent)

## What is the reciprocal of cot?

The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). The reciprocal tangent function is cotangent, expressed two ways: cot(theta)=1/tan(theta) or cot(theta)=cos(theta)/sin(theta).

## How do you find COT 45 degrees?

Daniel L. The value of cot45 is 1. You can get a right angled triangle with the other two angles of 45 degrees by drawing a diagonal in a square.

## What is the cot of 90 degrees?

The exact value of cot(90°) cot ( 90 ° ) is 0 .

## What is the value of cot inverse 1?

With inverse cotangent, we select the angle on the top half of the unit circle. Thus cot-1 (–1) = 135° or cot-1 (–1) = 3π/4. In other words, the range of cot-1 is defined to be the angles on the upper half of the unit circle as pictured below. The range of cot-1 is restricted to (0, 180°) or (0, π).

## How do you find the cot of an angle?

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.

## What is the value of cot 30?

The exact value of cot(30) is √3 .

## What is the value of cot 1?

Therefore, cot−1 x = nπ + α, where, (α ≠ 0, – π/2 ≤ α ≤ π/2) and ( – ∞ < x < ∞ ). Therefore, principal value of cot−1 √3 is π/6 and its general value = nπ + π/6.

## What is the COT 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 .

## How do you find the exact value of cot?

Trigonometry Examples Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cotangent is negative in the fourth quadrant. The exact value of cot(60) is 1√3 . Multiply 1√3 by √3√3 .

## Is cot an Arctan?

arctan(x) 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. arctan(x) is the angle whose tangent is x.

## What is cot the opposite of?

The cotangent is the reciprocal of the tangent. It is the ratio of the adjacent side to the opposite side in a right triangle.
