take the tangent of a number in swift

To take the tangent of a number in Swift, you can use the tan() function provided by the Foundation framework.

Here's an example:

main.swift
import Foundation

let angleInRadians = Double.pi / 4 // 45 degrees
let tangentValue = tan(angleInRadians)

print(tangentValue) // Output: 0.9999999999999999

In this example, we first imported the Foundation framework, which provides mathematical functions like tan(). We then defined an angle in radians (Double.pi / 4), and used the tan() function to find its tangent. Finally, we printed the result.
