Here, we are going to learn how to get the cosine value of the given angle in radian in Swift programming language?
Submitted by Nidhi, on June 22, 2021

Problem Solution:

Here, we will get the cosine value of the given angle using cos() function. The cos() function accepts an angle in radians as Double as a parameter and return the result to the calling function.

Program/Source Code:

The source code to get the cosine value of the given angle in radian is given below. The given program is compiled and executed successfully.

// Swift program to get the cosine value of 
// the given angle in radian

import Swift
import Foundation

var num:Double  = 14.234
var res:Double  = 0

res = cos(num)

print("Result: ",res)

Output:

Result:  -0.09668180163468348

...Program finished with exit code 0
Press ENTER to exit console.

Explanation:

In the above program, we imported a package Swift to use the print() function using the below statement,

import Swift;

To use mathematics and some standard functions, we need to import the foundation package using the below statement,

import Foundation;

Here, we created two double type variables num, res initialized with "14.234", "0.0". Then we found the cosine value of the specified angle in radian and printed the result on the console screen.
