Java - Math sin() Method
Description
The Java Math sin(double a) the trigonometric sine of an angle. Special cases −
If the argument is NaN or an infinity, then the result is NaN.
If the argument is zero, then the result is a zero with the same sign as the argument.
Syntax
public static double sin(double d)
Parameters
Here is the detail of parameters −
d − A double data type.
Return Value
This method returns the sine of the specified double value.
Example 1
In this example, we're showing the usage of Math.sin() method to get the sin of a double number. We've created a double variable x and initialized it with a given angle. Then using Math.toRadians() method we're retrieving the radian and then using Math.sin() method we've printed the sin value.
public class Test { public static void main(String args[]) { double degrees = 45.0; double radians = Math.toRadians(degrees); System.out.format("The value of pi is %.4f%n", Math.PI); System.out.format("The sine of %.1f degrees is %.4f%n", degrees, Math.sin(radians)); } }
This will produce the following result −
Output
The value of pi is 3.1416 The sine of 45.0 degrees is 0.7071
Example 2
In this example, we're showing the usage of Math.sin() method to get the sin of a float number. We've created a float variable x and initialized it with a given angle. Then using Math.toRadians() method we're retrieving the radian and then using Math.sin() method we've printed the sin value.
public class Test { public static void main(String args[]) { float degrees = (float)45.0; double radians = Math.toRadians(degrees); System.out.format("The value of pi is %.4f%n", Math.PI); System.out.format("The sine of %.1f degrees is %.4f%n", degrees, Math.sin(radians)); } }
This will produce the following result −
Output
The value of pi is 3.1416 The sine of 45.0 degrees is 0.7071
Example 3
In this example, we're showing the usage of Math.sin() method to get the sin of a zero value. We've created a float variable x and initialized it with a given angle for zero value. Then using Math.toRadians() method we're retrieving the radian and then using Math.sin() method we've printed the sin value.
public class Test { public static void main(String args[]) { float degrees = (float)0.0; double radians = Math.toRadians(degrees); System.out.format("The value of pi is %.4f%n", Math.PI); System.out.format("The sine of %.1f degrees is %.4f%n", degrees, Math.sin(radians)); } }
This will produce the following result −
Output
The value of pi is 3.1416 The sine of 0.0 degrees is 0.0000
