The code provided below gives a step-by-step approach for computing the cosine using a series expansion.#### Task OverviewYou are tasked with migrating the given cosine calculation into a new static method named `cosine`. This method should accept a single double input and return the estimated cosine value as a double output.Make sure to call this new method from the `main` method of your program and assign the returned value to the variable `estimate`.#### Java Code Example```javaimport java.util.Scanner;import java.lang.Math;public class CosineFromScratch{ /* The following code demonstrates how to estimate the cosine of a number. Your assignment is to migrate the calculation of the cosine into a new static method named cosine. The method should take one double input and return one double output. Make sure to call the method from main and set the variable estimate equal to the returned value. */ public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("\nGive me a number: "); double x = input.nextDouble(); // Trying to find cosine of this number double correct_cos = Math.cos(x); // START HERE: The following code goes into the method. // Source for the following: https://austinhenley.com/blog/cosine.html double num_terms = 10; int div = (int)(x / Math.PI); x = x - (div * Math.PI); int sign = -1; double estimate = 1.0; double inter = 1.0; double num = x * x; for (int i = 1; i <= num_terms; i++) { double comp = 2.0 * i; double den = comp * (comp - 1.0); inter *= num / den; estimate += inter * sign; sign *= -1; // flip the sign } // If div is odd, flip the estimate if (div % 2 != 0) { estimate = estimate * -1; } // STOP HERE }}```### Explanation1. **Input Handling:** The program begins by importing the necessary Java utilities and

The program uses the Scanner package which is used for taking user inputs during run time. The next…
