Question

How to use the math.Cosh() function to get the hyperbolic cosine of a number in Go

Answer 1

package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Println("math.Cosh(-1) =", math.Cosh(-1))
	fmt.Println("math.Cosh(1) =", math.Cosh(1))
	fmt.Println("math.Cosh(0) =", math.Cosh(0))
	fmt.Println("math.Cosh(-0) =", math.Cosh(-0))
	fmt.Println("math.Cosh(0.9) =", math.Cosh(0.9))
	fmt.Println("math.Cosh(math.Pi) =", math.Cosh(math.Pi))
	fmt.Println("math.Cosh(math.Pi * 2) =", math.Cosh(math.Pi*2))
	fmt.Println("math.Cosh(math.Pi / 2) =", math.Cosh(math.Pi/2))
	fmt.Println("math.Cosh(math.Pi / 3) =", math.Cosh(math.Pi/3))
}
