Question

Program the following in Java language.

Implement the following equation

3x4sin(180x) + 4x3 cos(90x) + x2sin(tan(45)) + 7x + 9cos(90x2 )

where x may be user defined value.

Answer 1

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        double x = Math.toRadians(new Scanner(System.in).nextDouble());
        System.out.println(3 * x * 4 * Math.sin(180 * x)
                + 4 * x * 3 * Math.cos(90 * x)
                + x * 2 * Math.sin(Math.tan(Math.toRadians(45)))
                + 7 * x
                + 9 * Math.cos(90 * x * 2));
    }
}
