Math.sin

Question

I am asked to create a program that takes an angle in degrees convert it into radians and give the sin cos and tan of the angle
I am unfamiliar with these methods and unsure how to set the method up
I have looked up the method details for all methods such as
sin
{code}public static double sin(double a){code}
I still do not have any clue, I do not want just an answer, I would rather be guided somewhere that I can figure this out on my own.
I try to look up the classes and methods on java but i just dont understand, this is my second java class and it still seems like a different lanuguage.
THanks for any help

Answer 1

a couple of corrections but I think this is perfect
the last code i posted after i converted to radians i still used my degree varible to detrimine my cos, sin, and tan
so i fixed it to use the converted radians
     public static void main(String[] args) {
          // Initialize variables
          double angdeg = 0;
          double csin = 0;
          double ccos = 0;
          double ctan = 0;
          double rad = 0;
          // User Input
          Scanner kb = new Scanner(System.in);
          System.out.print("Enter The Angle in Degrees");
          angdeg = kb.nextDouble();
          // Calculations
          rad = Math.toRadians(angdeg);
          csin = Math.sin(rad);
          ccos = Math.cos(rad);
          ctan = Math.tan(rad);
          // Output
          System.out.printf(" Angle (degs): %4.4f\n Angle (rads):  %6.4f\n Sine: %15.4f\n Cosine: %13.4f\n Tangent: %12.4f\n", angdeg, rad, csin, ccos, ctan);
}
