what can I do to improve my code while still getting the same output. I want to either make it smaller or learn some new techniques that I can implement.

here is my code:

import java.io.*; import java.lang.Math; public class Derivation { public static double f(double x) { return Math.pow(x,2)-Math.2sin(Math.pow(x,2))- Math.constant(1);

} public static void main(String argv[]) {

double h=1.0,x=2.0,fd,fdold; fdold=f(x); while(h>2.0E-12) { fd=(f(x+h)-f(x))/h; System.out.println(" h="+h+" f'(x)="+fd+" error="+(fd-fdold)); fdold=fd; h=h/2.0; } }

}
