take the cosecant of a number in go

To take the cosecant of a number in Go, you first need to import the math package. The math package provides various mathematical functions, including trigonometric functions like sine, cosine, tangent, and their inverses.

The cosecant is the reciprocal of the sine function. Therefore, in order to calculate the cosecant of a number in Go, you can first compute the sine of the number using the math.Sin() function, and then take its reciprocal using the 1.0 / operator.

Here is an example code snippet that calculates the cosecant of a number:

main.go
package main

import (
	"fmt"
	"math"
)

func main() {
	x := 45.0 // the number in degrees
	rad := x * math.Pi / 180.0 // convert degrees to radians
	csc := 1.0 / math.Sin(rad) // calculate cosecant
	fmt.Printf("cosecant of %v degrees is %v\n", x, csc)
}

In this code, we first define the number x in degrees. Then, we convert it to radians using the formula rad = x * pi / 180. We then calculate the cosecant using the formula csc = 1.0 / sin(rad). Finally, we print the result to the console using fmt.Printf(). Note that math.Pi is a constant in Go that represents the value of pi.
