cosh()

The cosh() method in Kotlin’s math class computes the hyperbolic cosine of a angle given in radians.

Syntax

import kotlin.math.*
val y = cosh(x)

x: An angle of type Double or Float.

Special cases:

• cosh(NaN) yields NaN
• cosh(+Inf|-Inf) yields +Inf

Example

The following code is basic implementation of math.cosh().

import kotlin.math.*
fun main(){
  val x = 30.0
  val y = cosh(x)

  //print results
  println(y)
}

This example will output:
