Question

Write a program that inputs from the user an angle (measured in degrees) then computes and prints: (the trigonometric sine of the angle in radians) squared + (the trigonometric cosine of the angle in radians) squared. Test your program on different degrees; if your program is working correctly, the result should be 1 each time (pythagorean trigonometric identity).

IN JAVA THANK YOU

Answer 1

//PythagoreanTrigonometricIdentity.java
import java.util.Scanner;
public class PythagoreanTrigonometricIdentity {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);
        System.out.print("Enter an angle (measured in degrees): ");
        double angle = scan.nextDouble();

        System.out.println(Math.pow(Math.sin(angle),2)+Math.pow(Math.cos(angle),2));
    }
}
