## What does arccos of 0 mean?

90 degrees
The arccosine of 0 is equal to the inverse cosine function of 0, which is equal to π/2 radians or 90 degrees: arccos 0 = cos-1 0 = π/2 rad = 90º

What is the exact value of arccos 0?

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

### Is arccos 0 an angle?

The arccos function is the inverse of the cosine function. It returns the angle whose cosine is a given number….For y = arccos x :

Range 0 ≤ y ≤ π 0 ° ≤ y ≤ 180 °
Domain − 1 ≤ x ≤ 1

What is arccos 0.5 solution?

arc cosine(0.5) = 60°

## What is the exact value of arccos 1?

The exact value of cos-1(1) is 0 .

What does arccos equal?

Arccosine is the inverse of the cosine function and thus it is one of the inverse trigonometric functions. Arccosine is pronounced as “arc cosine”. Arccosine of x can also be written as “acosx” (or) “cos-1x” or “arccos”. If f and f-1 are inverse functions of each other, then f(x) = y ⇒ x = f-1(y).

### How do you convert arccos to degrees?

Arccos(x) calculator. Inverse cosine calculator….Arccos table.

x arccos(x)
-0.5 120° 2π/3
0 90° π/2
0.5 60° π/3

What is arccos on a calculator?

In mathematics, the inverse trigonometric functions are the inverse functions of the trigonometric functions. Specifically, the arccos is the inverse of the cosine. It is normally represented by arccos(θ) or cos-1(θ).

## What is the arccos of 2?

Since the cosine function has output values from -1 to 1, the arccosine function has input values from -1 to 1. So arccos x is undefined for x=2.

What is arccos calculator?

Arccos function The arccos is used to obtain an angle from the cosine trigonometric ratio, which is the ratio between the side adjacent to the angle and the hypotenuse in a right triangle. The function spans from -1 to 1, and so do the results from our arccos calculator.

### Is arccot the same as cot 1?

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 the arccos (x)?

The Arccos (x) is also referred to as the inverse cosine calculator. It is used to calculate the inverse of a cosine. This calculator has a single text field and there controls.

## What is the value of arccos = cos-1?

arccos (x) = cos -1 (x) For example, If the cosine of 60° is 0.5: cos (60°) = 0.5 Then the arccos of 0.5 is 60°:
