take the cosecant of a number in swift

To take the cosecant of a number in Swift, you can use the sin(_:) function from the Foundation library and divide 1 by its result. Here's an example:

main.swift
import Foundation

let angle = 45.0
let sine = sin(angle * Double.pi / 180)
let cosecant = 1 / sine

print(cosecant) // Output: 1.414213562373095

8 lines

In this example, we first convert the angle to radians by multiplying it with Double.pi / 180. Then, we calculate the sine of the angle using the sin(_:) function, and finally, we divide 1 by the sine to get the cosecant. The result is printed to the console.
