.acos()

The .acos() method in Kotlin’s math class is used to calculate the arccosine of a given value, returning the corresponding angle in radians.

Syntax

import kotlin.math.*
val angle = acos(value)

value: The given value to be used in the arccosine calculation. The value should be in the range -1 to 1.

The .acos() method returns a value of type double representing the angle in radians. The result will be in the range 0 to PI.

Example

This example shows how to use the acos() method to calculate the arccosine of a value:

import kotlin.math.*

fun main() {
    val value = 0.5
    val angle = acos(value)
    println("The arccosine of $value is $angle radians.")
}

The output of this code will be:

The arccosine of 0.5 is 1.0471975511965979 radians.
