Java Math.sin() to get sin vlaue of input angle in radian

Math.sin() returns the trigonometric sin value of an angle in radian.
Syntax

Math.sin(angle_in_radian)

Note that all input numbers are in Radians.

Here are some examples.

System.out.println(Math.sin(Math.PI));	//1.2246467991473532E-16
System.out.println(Math.sin(Math.PI/2));//1.0
System.out.println(Math.sin(2)); 	//0.9092974268256817
System.out.println(Math.sin(1.22));	//0.9390993563190676
System.out.println(Math.sin(-1.22)); 	//-0.9390993563190676
System.out.println(Math.sin(0)); 		// 0.0

We can use toRadians to convert degree value to radian.
Math.round() to rounds a floot or double data type to nearest integer value

System.out.println(Math.round((Math.sin(Math.toRadians(180)))));//0
System.out.println((Math.sin(Math.toRadians(180))));//1.2246467991473532E-16
System.out.println(Math.sin(Math.toRadians(90))); //1.0
System.out.println(Math.sin(Math.PI)); 		//1.2246467991473532E-16
System.out.println(Math.sin(Math.PI/2));	//1.0
