math - Write a calculator for the identity sin² + cos² = 1 -


here's wrote:

public class math {   public static void main (string[] args){     double degrees = double.parsedouble(args[0]);     double s = math.sin(degrees);     double c = math.cos(degrees);     double x = s*s + c*s;     system.out.println(x);   } }

i want enter number args[0] goes sin() , cos(). want add 2 variables making equal 1, because sin² + cos² = 1. doing wrong?

edit: made changes code s*s + c*c, i'm still getting same error.

i'm getting error:

2 errors found: file:...  [line: 4] error: cannot find symbol   symbol:   method sin(double)   location: class math file:...  [line: 5] error: cannot find symbol   symbol:   method cos(double)   location: class math

you not squaring each term calculating , printing sin(x) + cos(x). replace

double x = s + c;

with

double x = s*s + c*c;

and should right behaviour.
