### 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 mainimport (    "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)}`
