Go – How to get cosine of the radian number in go

Here, We will learn how to get cosine of the radian number in go. We can get it by using Cos() function in math package in go golang.

Function prototype:

func Cos(no float64) float64

Return value:

Cos() function in math package returns
the cosine of the radian number.

Example with code:

package main

import (
  "fmt"
  "math"
)

func main() {

  no := math.Cos(1)
  fmt.Printf("%.2f\n", no)

  no = math.Cos(0.25)
  fmt.Printf("%.2f\n", no)

  no = math.Cos(0.75)
  fmt.Printf("%.2f\n", no)

  no = math.Cos(math.Pi/2)
  fmt.Printf("%.2f\n", no)
}

Output:

0.54
0.97
0.73
0.00
