Java's Math library gives you methods to convert between degrees and radians: toRadians and toDegrees:
public class examples
{
public static void main(String[] args)
{
System.out.println( Math.toRadians( 180 ) ) ;
System.out.println( Math.toDegrees( Math.PI ) ) ;
}
}
If your input is in degrees, you need to convert the number going in to sin to radians:
double angle = 90 ;
double result = Math.sin( Math.toRadians( angle ) ) ;
System.out.println( result ) ;

Using Math.sin with Degrees | Baeldung
January 25, 2024 - We can see this principle in action by taking a look at the Math.sin method, one of the many that Java provides: ... It’s equivalent to the mathematical sine function and it expects its input to be in radians. So, let’s say that we have an angle we know to be in degrees:

if your radian value is a, then multiply the radian value with (22/7)/180.
The code would be like this for the above situation:-
double rad = 45 // value in radians.
double deg ;
deg = rad * Math.PI/180; // value of rad in degrees.

Note: If the argument is zero, then the result of the sin() method is also zero with the same sign as the argument. import java.lang.Math; class Main { public static void main(String[] args) { // create variable in Degree double a = 30; double b = 45; // convert to radians a = Math.toRadians(a); b = Math.toRadians(b); // print the sine value System.out.println(Math.sin(a)); // 0.49999999999999994 System.out.println(Math.sin(b)); // 0.7071067811865475 // sin() with 0 as its argument System.out.println(Math.sin(0.0)); // 0.0 } } In the above example, we have imported the java.lang.Math package.

First of all, you should read the javadoc. sin(double) takes a double in parameter which is the angle in radians like said in the documentation. You'll also find on the linked page that sqrt takes a double as well.
Then, you should know that java can perform non-destructive conversion automatically. So if a method takes a double and you have a long, it will be no problem, since there's no loss in the conversion long -> double. The reverse is false, so Java refuse ton compile.
For the radians conversion, you'll find a toRadians method in the Math class.

- If you have value in degrees, just do
degrees * Math.PI / 180. Or better use function suggested by coobird in the comment (didn't know of it). - Yes, you can pass any double value in it. (Any number, for that matter.)
- No, both functions take
doubleparameter. Check the docs.

October 17, 2022 - Taking the sine of it is then taking the sine of the sine, not what you want. If you do take the sine of 0.8, then Java takes this 0.8 to be the angle in radians. The relation between radians and degrees is 2 * Pi radians = 360 degrees So 1 radian is equal (360 / (2 * Pi)) degrees.
