Trigonometry with Go Language - Sin, Cos, Tan Functions Examples

Package math provides functions to calculate Trigonometric functions values.

Program to demonstrate how to calculate Trigonometric functions values in Go,

package main
import (
    "fmt"
    "math"
)
func main() {
    var degrees float64
    fmt.Println("Enter value of angle in degrees : ")
    _, err := fmt.Scanf("%f", &degrees)
    if err != nil {
        fmt.Println(err)
    }
    //calculate the sine
    s := math.Sin(degrees)
    fmt.Println("The Sine of ", degrees, " degrees is : ", s)
    //calculate the cosine
    c := math.Cos(degrees)
    fmt.Println("The Cosine of ", degrees, " degrees is : ", c)
    //calculate the tan
    t := math.Tan(degrees)
    fmt.Println("The Tangent of ", degrees, " degrees is : ", t)
    //calculate the sec
    se := 1 / math.Sin(degrees)
    fmt.Println("The Sec of ", degrees, " degrees is : ", se)
    //calculate the cosec
    co := 1 / math.Cos(degrees)
    fmt.Println("The Cosec of ", degrees, " degrees is : ", co)
    //calculate the cotangent
    cot := 1 / math.Tan(degrees)
    fmt.Println("The Cotangent of ", degrees, " degrees is : ", cot)
}

Output:
