Arccos Calculator

A web-based mini-computer to work out the opposite cosine capability arccos(x) in radians and degrees.Use arccos mini-computer to compute the arccosine of a number without any problem. Upholds contribution of either decimal numbers (for example 0.5, - 0.5) or divisions (for example 1/2, - 1/2).

Arccos definition

The arccosine capability is the opposite capability of cos(x).

arccos(x) = cos^-1(x)

For instance, If the cosine of 60° is 0.5:

cos(60°) = 0.5

Then the arccos of 0.5 is 60°:

arccos(0.5) = cos^-1(0.5) = 60°

How to utilize the arccos (x) calculator?

Enter x as a genuine number, inside the space of arccos capability with the end goal that - 1 ≤ x ≤ 1 and the quantity of decimal spots wanted then press "enter". Two responses are shown: one in radians and the second in degrees.

What is the opposite of cosine (arccos)?

Arccos is the opposite of a geometrical capability - explicitly, the converse of the cosine capability. Notwithstanding, as geometrical capabilities are occasional, then, from a severe perspective, they can't be transformed. We can manage that issue by picking a span where the essential capability is monotonic. You can pick various reaches, yet for cosine the normal decision is [0,π]. This reach is known as the arrangement of head values.

Arccos(x) is the most usually utilized documentation, as cos^-1x might be deluding - recall that reverse cosine isn't equivalent to the corresponding of the capability (all in all, raising to the power - 1):

cos^-1x ≠ 1/cos(x)

Arccos capability :- The arccos (arcus cosine, arccosine) is one of the opposite geometrical capabilities (antitrigonometric capabilities, arcus works) and is the converse of the cosine capability. It is now and again composed as cos^-1(x), yet this documentation ought to be stayed away from as it very well may be mistaken for a type documentation (force of, raised to the force of). The arccos is utilized to get a point from the cosine geometrical proportion, which is the proportion between the side neighboring the point and the hypotenuse in a right triangle.

The capability ranges from - 1 to 1, thus do the outcomes from our arccos adding machine. The scope of the point values is ordinarily somewhere in the range of 0° and 180°. There are various arccos rules, similar to that cos(arccos(x)) = x, or that arccosα + arccosβ = arccos(αβ - √((1-α²)(1-β²)), as well as sine of the arccosine: sin(arccos(x)) = √(1-x²), which can help you in geometry calculus.
