how I can see how math.cos method in java calculate the square root?

Question

I am not a genius mathematical scientist

but I'm trying to see how sqrt , cos , sin ,... functions do the calculations

I opened the file strictMath.java which is inside 'C:\Program Files\Java\jdk1.7.0_17\src.zip'

and that is what I found:

public static native double sin(double a);

public static native double cos(double a);

public static native double sqrt(double a);

I didnt see the code that each function use to calculate

so anyone can tell me how these functions work?

The Math.cos() method does not calculate the square root. Your title is meaningless. — user207421, Sep 25 '13 at 12:21
